The United States, invoking our original jurisdiction under Art. III, § 2, of the Constitution, brought this suit against the States of Louisiana, Texas, Mississippi, Alabama, and Florida, seeking a declaration that it is entitled to exclusive possession of, and full dominion and power over, the lands, minerals, and other natural resources underlying the waters of the Gulf of Mexico more than three geographical miles seaward from the coast of each State and extending to the edge of the Continental Shelf.1 The complaint also asks that the States be enjoined from interfering with the rights of the United States in that area, and that they be required to account for all sums of money derived by them therefrom since June 5, 1950.2 The case is now before us on the motions of the United States for judgment on the pleadings and for dismissal of Alabama's cross bill seeking to establish its rights to such submerged lands and resources within three marine leagues of its coast.

The controversy is another phase of the more than 20 years' dispute between the coastal States and the Federal Government over their respective rights to exploit the oil and other natural resources of offshore submerged lands. In 1947 this Court held that, as against California, the United States possessed paramount rights in such lands underlying the Pacific Ocean seaward of the low-water mark on the coast of California and outside of inland waters. United States v. State of California, 332 U.S. 19, 67 S.Ct. 1658, 91 L.Ed. 1889; 332 U.S. 804, 68 S.Ct., 20, 92 L.Ed. 382. And on June 5, 1950, the Court, following the principles announced in the California case, made like holdings with respect to submerged lands in the Gulf of Mexico similarly lying off the coasts of Louisiana and Texas, and directed both States to account to the United States for all sums derived from natural resources in those areas after that date. United States v. State of Louisiana, 339 U.S. 699, 70 S.Ct. 914, 94 L.Ed. 1216; 340 U.S. 899, 71 S.Ct. 275, 95 L.Ed. 651; United States v. State of Texas, 339 U.S. 707, 70 S.Ct. 918, 94 L.Ed. 1221;340 U.S. 900, 71 S.Ct. 276, 95 L.Ed. 652.3

On May 22, 1953, Congress, following earlier repeated unsuccessful attempts at legislation dealing with state and federal rights in submerged lands,4 passed the Submerged Lands Act, 67 Stat. 29, 43 U.S.C. §§ 1301—1315, 43 U.S.C.A. §§ 1301 1315. By that Act the United States relinquished to the coastal States all of its rights in such lands within certain geographical limits, and confirmed its own rights therein beyond those limits. The Act was sustained in State of Alabama v. State of Texas, 347 U.S. 272, 74 S.Ct. 481, 98 L.Ed. 689, as a constitutional exercise of Congress' power to dispose of federal property, Const.Art. IV, § 3, cl. 2. Since the Act concededly did not impair the validity of the California, Louisiana, and Texas cases, which are admittedly applicable to all coastal States, this case draws in question only the geographic extent to which the statute ceded to the States the federal rights established by those decisions.

The purposes of the Submerged Lands Act are described in its title as follows:

'To confirm and establish the titles of the States to lands beneath navigable waters within State boundaries and to the natural resources within such lands and waters, to provide for the use and control of said lands and resources, and to confirm the jurisdiction and control of the United States over the natural resources of the seabed of the Continental Shelf seaward of State boundaries.'

To effectuate these purposes the Act, in pertinent part—

1. relinquishes to the States the entire interest of the United States in all lands beneath navigable waters within state boundaries (§ 3, 43 U.S.C. § 1311, 43 U.S.C.A. § 1311);5

2. defines that area in terms of state boundaries 'as they existed at the time (a) State became a member of the Union, or as heretofore approved by the Congress,' not extending, however, seaward from the coast of any State more than three marine leagues6 in the Gulf of Mexico or more than three geographical miles in the Atlantic and Pacific Oceans (§ 2, 43 U.S.C. § 1301, 43 U.S.C.A. § 1301);7

3. confirms to each State a seaward boundary of three geographical miles, without 'questioning or in any manner prejudicing the existence of any State's seaward boundary beyond three geographical miles if it was so provided by its constitution or laws prior to or at the time such State became a member of the Union, or if it has been heretofore approved by Congress' (§ 4, 43 U.S.C. § 1312, 43 U.S.C.A. § 1312);8 and

4. For purposes of commerce, navigation, national defense, and international affairs, reserves to the United States all constitutional powers of regulation and control over the areas within which the proprietary interests of the States are recognized (§ 6(a), 43 U.S.C. § 1314, 43 U.S.C.A. § 1314);9 and retains in the United States all rights in submerged lands lying beyond those areas to the seaward limits of the Continental Shelf (§ 9, 43 U.S.C. § 1302, 43 U.S.C.A. § 1302).10

The United States concedes that the statute grants to each of the defendant States submerged land rights in the Gulf of Mexico to the extent of three geographical miles, but contends that none of them is entitled to anything more. The States, conceding that three leagues is the limit of the statute's grant in the Gulf contend that each of them is entitled to that much. The wide-ranging arguments of the parties, reflecting no doubt the magnitude of the economic interests at stake,11 can be reduced to the following basic contentions:

The Government starts with the premise that the Act grants submerged land rights to a distance of more than three miles only to the extent that a Gulf State can show, in accordance with § 2(b) of the Act, either that it had a legally established seaward boundary in excess of three miles at the time of its admission to the Union, or that such a boundary was thereafter approved for it by Congress prior to the passage of the Submerged Lands Act. It is contended that the Act did not purport to determine, fix, or change the boundary of any State, but left it to the courts to ascertain whether a particular State had a seaward boundary meeting either of these requirements. The Government then urges, as to any State relying on its original seaward boundary, that the Act contemplates as the measure of the grant a boundary which existed subsequent to a State's admission to the Union, and not one which existed only prior to admission—in other words, a boundary carrying the legal consequences of the event of admission. It reasons from this that since a State's seaward boundary cannot be greater than the national maritime boundary, and since the national boundary was at all relevant times never greater than three miles, no State could have had a seaward boundary in excess of three miles, regardless of what it may have claimed prior to admission. Further, the Government undertakes to show that, irrespective of the extent of the national maritime boundary, none of these States ever had a valid seaward boundary in excess of three miles, even prior to admission, and that no such boundary was thereafter approved by Congress for any State.

The States, on the other hand, make several alternative arguments. At one extreme, they contend that the Submerged Lands Act ipso facto makes a three-league grant to all the Gulf States, or at least that the Act by its terms establishes the seaward boundary of some States, notably Texas and Florida, at three leagues. Alternatively, they argue that if the extent of such state boundaries 'at the time' of admission was left to judicial determination, then the controlling inquiry is what seaward boundary each State had just prior to admission. If, however, the Act contemplates a boundary as fixed by the event of admission, each State contends that Congress fixed for it a three-league Gulf boundary, and that whatever may have been the extent of the national maritime boundary at the time is an irrelevant factor. Florida further contends that when it was readmitted to the Union in 1868, Congress approved for it a three-league Gulf boundary. And finally the States argue that if the national boundary is in any way relevant, it has at all material times in fact been at three leagues in the Gulf of Mexico.

Both sides have presented in support of their respective positions a massive array of historical documents, of which we take judicial notice, and substantially agree that all the issues tendered can properly be disposed of on the basis of the pleadings and such documents.

In this opinion we consider the issues arising in common between the Government and all the defendant States, and the particular claims of Texas, Louisiana, Mississippi, and Alabama, all of which depend upon their original admission boundaries. The particular claims of Florida, which involve primarily its readmission boundary, are considered in a separate opinion. 363 U.S. 121, 80 S.Ct. 1026.

The Common Issues.

A. The Statute On Its Face.

The States' contention that the Act ipso facto grants them submerged land rights of three leagues in the Gulf may be shortly answered. The terms of the statute require rejection of such a construction. Rather the measure of the grant in excess of three miles is made to depend entirely upon the location of a State's original or later Congressionally approved maritime boundary, subject only to the three-league limitation of the grant.

We turn next to the question whether, as the States contend, the first of the two alternative requirements of § 2—a boundary which 'existed at the time such State became a member of the Union'—is satisfied merely by a showing a preadmission boundary, or whether, as the Government claims, that requirement contemplates only a boundary that carries the legal consequences of the event of admission. While it is manifest that the second requirement of § 2—a boundary which was 'heretofore approved by the Congress'—must take into account the effect of Congressional action, it is not clear from the face of the statute that the same is true of the first requirement—a boundary 'as it existed at the time (a) State became a member of the Union.'

The Government argues that in construing the first requirement of § 2 the effect of Congressional action cannot be ignored because to do so would be to measure the boundary prior to the time a State became a member of the Union, and 'at the time' cannot mean 'prior to the time.' However, it might be contended with equal force that to take account of the effect of Congressional action would be to measure the boundary after the time the State became a member of the Union, and 'at the time' cannot mean 'after the time.' Indeed, if 'at the time' were to be taken in a perfectly literal sense, it could refer only to the timeless instant before which the consequences of not being a State would obtain, and after which the consequences of statehood would follow, leaving unanswered the question whether the effect of Congressional action was to be considered or not. In short, if the term is to be given content it must be read as referring either to some time before or after the instant of admission, or to both times.

As an aid to construction of 'at the time' in § 2, the Government points to § 4, the last sentence of which states:

'Nothing in this section is to be construed as questioning or in any manner prejudicing the existence of any State's seaward boundary beyond three geographical miles if it was so provided by its constitution or laws prior to or at the time such State became a member of the Union, or if it has been heretofore approved by Congress.' (Emphasis supplied.)

It is urged that the disjunctive use of the terms 'prior to' and 'at the time' shows that the latter must have been used to refer to the time after admission, since the phraseology would otherwise be redundant, and that such meaning should also be attributed to the same term in § 2, thereby including the effect of Congressional action. But, as has already been indicated, 'at the time' inherently can also be taken as referring to the preadmission period, thereby excluding the effect of such action. And on that basis there would be no redundancy in the phrase 'prior to or at the time' if 'at the time' meant immediately before the instant of admission and 'prior to' referred to times substantially prior to admission; yet this would nonetheless exclude the effect of Congressional action. So far as the statute itself is concerned, the Government's argument is thus inconclusive.

Nor do the States' arguments upon the face of the statute illumine the meaning of 'at the time' as used in § 2. They contend that the meaning of § 2 is explained or clarified by the last sentence of § 4. According to them, a boundary 'existed at the time (a) State became a member of the Union' (§ 2) if 'it was so provided by its constitution or laws prior to or at the time such State became a member of the Union * * *.' § 4. Under this view, whatever the meaning of 'at the time,' the existence of a state constitutional or statutory three-league provision prior to admission would conclusively establish the boundary contemplated by the Act, irrespective of the character of Congressional action upon admission. However, this provision appears not in the definitional or granting sections of the statute (§§ 2 or 3), but in § 4, the purpose of which is to approve and confirm the boundaries of all States at three miles, and to negative any prejudice which might thereby result to claims in excess of three miles. It thus does not define the grant, but at most describes the claims protected from prejudice by § 4 in terms of their most likely nature. A fair reading of the section does not point to the conclusion that claims of this nature were deemed to be self-proving.

Finally, there is no indication on the face of the statute whether the Executive policy of the United States on the extent of territorial waters is a relevant circumstance in ascertaining the location of state seaward boundaries for purposes of the Act.

Because the statute on its face is inconclusive as to these issues, we turn to the legislative history.

B. The Legislative History.

This Court early held that the 13 original States, by virtue of the sovereignty acquired through revolution against the Crown, owned the lands beneath navigable inland waters within their territorial boundaries, and that each subsequently admitted State acquired similar rights as an inseparable attribute of the equal sovereignty guaranteed to it upon admission. Pollard's Lessee v. Hagan, 3 How. 212, 11 L.Ed. 565.12 It was assumed by many, and not without reason,13 that the same rule would be applied to lands beneath navigable waters of the marginal sea, that is, beyond low-water mark and the outer limit of inland waters. However, beginning in the 1930's, the Federal Government, while conceding the validity of the Pollard rule as to inland waters, disputed its applicability to submerged lands beyond that limit, and claimed ownership of those lands for the United States.14 The controversy centered primarily on the ownership of the oil-rich submerged lands off the coast of California. The State maintained that its original constitution, adopted in 1849 before it was admitted to the Union, established a seaward boundary three English miles from the coast,15 that this boundary was ratified by the Act of Congress admitting it to the Union, and that therefore under the Pollard rule, it was entitled to all submerged lands lying within three English miles of its coast. This Court refused so to apply Pollard, and held in the California case and the subsequent Louisiana and Texas cases, supra, that paramount rights in the marginal sea are an attribute of national rather than state sovereignty, irrespective of the location of state seaward boundaries.

Meanwhile an extended series of attempts was underway to secure Congressional legislation vesting in the States the ownership of those lands which would be theirs under an application of the Pollard rule to the marginal sea.16 It was strongly urged, both before and after the California decision that because the States had for many years relied on the applicability of the Pollard rule to the marginal sea, it was just and equitable that they be definitively given the rights which follow from such an application of the rule, and the California, Louisiana, and Texas cases were severely criticized for not having so applied it.17

Thus virtually every 'quitclaim' measure introduced between 1945 and 1953, when the Submerged Lands Act was ultimately enacted, framed the grant in terms of 'lands beneath navigable waters within State boundaries.' This framework was employed because the sponsors understood this Court to have established, prior to the California decision, a rule of state ownership itself defined in terms of state territorial boundaries, whether located at or below low-water mark.18 Since, however, none of the cases which had applied that rule involved lands below low-water mark, and since the California and subsequent Louisiana and Texas cases adopted for such lands a rule which does not depend upon state boundaries, this Court has never had occasion to consider the precise nature and method of determining state territorial boundaries in the open sea, such as would circumscribe the extent of state ownership of offshore lands under an application of the Pollard rule. Because Congress, in the exercise of its constitutional power to dispose of federal property, has chosen so to frame its grant, we are now called on to resolve such questions in light of the Act's history and purposes.

From the very outset, the sponsors of 'quitclaim' legislation believed that all States were entitled to at least three miles of coastal submerged lands.19 The earliest bills confirmed to the States all lands beneath navigable waters within their boundaries, and defined 'lands beneath navigable waters' to include at least all lands lying within three geographical miles of the coast of each State.20 However, they contained no definition of'boundaries,' and it was apparently assumed that the boundaries of all States extended at least three miles.21 Opponents of such legislation quickly pointed out that while California based its three-mile claim on an expressly defined maritime boundary, many, if not most, of the coastal States lacked such a boundary,22 and that therefore, such States could not avail themselves of the Pollard rule, the applicability of which is restricted to areas within the actual territorial boundaries of the State, even assuming the rule to be capable of application beyond low-water mark.23 Proponents of the legislation alleged it to be defective in that it granted only those lands beneath navigable waters which lay within state boundaries, and that this Court in the California case, while not expressly passing on the question, had cast doubt on whether any of the original States ever had a boundary beyond its coast.24 As a result, a new section was added, substantially similar to the second and third sentences of § 4 of the present Act (see note 8, 363 U.S. 10, 80 S.Ct. 968), which permitted each State which had not already done so to extend its boundary seaward three miles and approved all such extensions theretofore or thereafter made, without prejudice to any State's claim that its boundary extended beyond three miles.25

It is not entirely clear on what theory Congress thus concluded that each State owned the submerged lands within three miles of its coast, irrespective of the existence of an expressly defined seaward boundary to that distance. It was substantially agreed that the 13 original Colonies owned the lands within three miles of their coasts because of their sovereignty and the alleged international custom which permitted a nation to extend its territorial jurisdiction that far.26 Some proponents of the legislation seem to have concluded that therefore, not only did the original States retain such rights after formation of the Union, but that subsequently admitted States acquired similar rights within three miles, irrespective of the location of their boundaries, by the operation of the equal-footing clause.27 It was also suggested that state ownership within three miles came about by operation of federal law because of the Federal Government's assumed adherence to the three-mile limit of territorial waters.28 While some speakers maintained that these factors in effect gave each State a three-mile maritime boundary,29 others eschewed technical reliance on the matter of boundaries and thought it sufficient that the Pollard rule had always been thought to confer ownership on the State of lands within three miles of the coast and that the States ought to be restored to the position they believed they had formerly occupied.30 And there is some suggestion that since many States, under the Congressional view of Pollard, had indisputable claims to three miles of submerged lands, the remainder ought to be treated on a parity whether or not their claims were technically justified.31 The upshot of all of these differing views was the confirmation of each coastal State's seaward boundary at three geographical miles.

Whatever may have been the uncertainty attending the relevance of state boundaries with respect to rights in submerged lands within three miles of the coast, we find a clear understanding by Congress that the question of rights beyond three miles turned on the existence of an expressly defined state boundary beyond three miles. Congress was aware that several States claimed such a boundary. Texas throughout repeatedly asserted its claim that when an independent republic its statutes established a three-league maritime boundary, and that the United States ratified that boundary when Texas was admitted to the Union and permitted Texas to retain its own public lands.32 Florida repeatedly asserted its claim that subsequent to its secession at the time of the Civil War, it framed a constitution which established a three-league boundary along its Gulf coast, and that such boundary was ratified when Congress in 1868, 15 Stat. 73, approved the State's constitution and readmitted it to the Union.33 Louisiana asserted that the Act of Congress admitting it to the Union in 1812, 2 Stat. 701, fixed for it a three-league maritime boundary by virtue of the provision which includes within the State 'all islands within three leagues of the coast.'34 And it was suggested that Mississippi and Alabama might claim boundaries six leagues in the Gulf because of similar provisions in the Acts admitting them to the Union.35

It was recognized that if the legal existence of such boundaries could be established, they would clearly entitle the respective States to submerged land rights to that distance under an application of the Pollard rule to the marginal sea. Hence, while a three-mile boundary was expressly confirmed for all coastal States, the right of the Gulf States to prove boundaries in excess of three miles was preserved. This treatment of the matter was carried into all the numerous 'quitclaim' bills by language similar to that found in § 4 of the present Act, confirming all coastal state boundaries at three miles and negating any prejudice to boundary claims in excess of that.36 Repeated expressions of the Act's sponsors make it absolutely clear that no boundary in excess of three miles was fixed for any State, but that a State would have to establish the existence of such a boundary in judicial proceedings.37 The many individual expressions of views as to the location of particular state boundaries—notably statements that the effect of the Act would be to give Texas and Florida three leagues of submerged land rights38—while undoubtedly representing the sincere beliefs of the speakers, cannot serve to relieve this Court from making an independent judicial inquiry and adjudication on the subject, as contemplated by Congress.

The earlier 'quitclaim' bills defined the grant in terms of presently existing boundaries,39 since such boundaries would have circumscribed the lands owned by the States under an application of Pollard to the marginal sea. However, the sponsors of these measures soon recognized that present boundaries could be ascertained only by reference to historic events. The claims advanced by the Gulf States during consideration of earlier bills were identical to those subsequently asserted.40 The theory of those claims, as we have noted, depended either, as in the cases of Texas and Florida, upon a constitutional or statutory provision allegedly ratified by Congressional acquiescence, or, as in the cases of Louisiana, Mississippi, and Alabama, upon express Congressional action. Indeed, it could hardly have been contended that Congressional action surrounding the event of admission was not relevant to the determination of present boundaries. Some suggestions were made, however, that States might by their own action have effectively extended, or be able to extend, their boundaries subsequent to admission.41 To exclude the possibility that States might be able to establish present boundaries based on extravagant unilateral extensions, such as those recently made by Texas and Louisiana,42 subsequent drafts of the bill introduced the twofold test of the present Act—boundaries which existed at the time of admission and boundaries heretofore approved by Congress.43 It is apparent that the purpose of the change was not to alter the basic theory of the grant, but to assure that the determination of boundaries would be made in accordance with that theory—that the States should be 'restored' to the ownership of submerged lands within their present boundaries, determined, however, by the historic action taken with respect to them jointly by Congress and the State.44 It was such action that the framers of this legislation conceived to fix the States' boundaries against subsequent change without their consent and therefore to confer upon them the long-standing equities which the measure was intended to recognize.45

Somewhat later, the last sentence of the present Act's § 4 was added, for the specific purpose of assuring that the boundary claims of Texas and Florida would be preserved.46 The first part of the sentence (see note 8, 363 U.S. 10, 80 S.Ct. 968), intended to refer to Texas alone, protects the State's claim to a three-league boundary as 'provided by its constitution or laws prior to or at the time such State became a member of the Union.' That claim, however, was asserted to rest not only on its statute but also on the action of Congress in admitting it to the Union.47 If any doubt could remain that the event of admission is a vital circumstance in ascertaining the location of boundaries which existed 'at the time' of admission within the meaning of the Submerged Lands Act, it is conclusively dispelled by repeated statements of its proponents to that effect.48

We conclude, therefore, that the States' contention that preadmission boundaries, standing alone, suffice to meet the requirements of the statute is not tenable.

3. The Question of Executive Policy Respecting the 'Three-Mile Limit.'

During consideration of the various 'quitclaim' bills between 1945 and 1953, the suggestion that international questions might be raised by the bill constantly recurred. It was asserted that the United States might be embarrassed in its dealings with other nations, first, by permitting States to exercise rights in submerged lands beyond three miles,49 and, second, by recognizing that the boundaries of some States might extend beyond three miles from the coast.50 The first objection was laid to rest by the testimony of Jack B. Tate, Deputy Legal Adviser to the State Department. Mr. Tate stated that exploitation of submerged lands involved a jurisdiction of a very special and limited character, and he assured the Committee that assertion of such a jurisdiction beyond three miles would not conflict with international law or the traditional United States position on the extent of territorial waters. He concluded that since the United States had already asserted exclusive rights in the Continental Shelf as against the world, the question to what extent those rights were to be exercised by the Federal Government and to what extent by the States was one of wholly domestic concern within the power of Congress to resolve.51

The second objection, however—that to recognize by the Act the possible existence of some state maritime boundaries beyond three miles would embarrass this country in its dealings with other nations—was persistently pressed by the State Department and by opponents of the bill. The bill's supporters consistently took the position that under the Pollard rule as they understood it, the extent of a State's submerged land rights in excess of three miles depended entirely upon the location of its maritime boundary as fixed by historical events,52 and that to the extent a State's boundary had been so fixed beyond three miles, it constituted an exception to this country's assumed adherence to the three-mile limit. The admission of Texas and the readmission of Florida were repeatedly asserted as instances where Congress had made exceptions to the three-mile policy, purportedly based on the shallowness of waters in the Gulf and the alleged Spanish custom of claiming three leagues of territorial waters.53

The State Department, confronted with this argument, tenaciously maintained that it had never recognized any boundaries in excess of three miles.54 It insisted that by virtue of federal supremacy in the field of foreign relations, the territorial claims of the States could not exceed those of the Nation, and that, therefore, if the bill recognized the effectiveness of the relied-on historical events to fix boundaries beyond three miles despite the State Department's refusal so to recognize them, the bill would violate this country's consistent foreign policy. The Government now urges in this case a closely similar contention. It says that the Submerged Lands Act did not establish any formula for the ascertainment of state boundaries but left them to be judicially determined, and that because of federal supremacy in the field of foreign relations, this Court must hold that the Executive policy of claiming no more than three miles of territorial waters—allegedly in force at all relevant times, and evidenced by the State Department's consistent refusal to recognize boundaries in excess of three miles—worked a decisive limitation upon the extent of all state maritime boundaries for purposes of this Act.55

We agree that the Submerged Lands Act does not contain any formula to be followed in the judicial ascertainment of state boundaries, and that therefore, we must determine, as an independent matter, whether boundaries, for purposes of the Act, are to be taken as fixed by historical events such as those pointed to in the Congressional hearings and debates, or whether they must be regarded as limited by Executive policy on the extent of territorial waters, as contended by the Government. However, in light of the purely domestic purposes of the Act, we see no irreconcilable conflict between the Executive policy relied on by the Government and the historical events claimed to have fixed seaward boundaries for some States in excess of three miles. We think that the Government's contentions on this score rest on an oversimplification of the problem.

A land boundary between two States is an easily understood concept. It marks the place where the full sovereignty of one State ends and that of the other begins. The concept of a boundary in the sea, however, is a more elusive one. The high seas, as distinguished from inland waters, are generally conceded by modern nations to be subject to the exclusive sovereignty of no single nation.56 It is recognized, however, that a nation may extend its national authority into the adjacent sea to a limited distance for various purposes. For hundreds of years, nations have asserted the right to fish, to control smuggling, and to enforce sanitary measures within varying distances from their seacoasts.57 Early in this country's history, the modern notion had begun to develop that a country is entitled to full territorial jurisdiction over a belt of waters adjoining its coast.58 However, even this jurisdiction is limited by the right of foreign vessels to innocent passage.59 The extent to which a nation can extend its power into the sea for any purpose is subject to the consent of other nations, and assertions of jurisdiction to different distances may be recognized for different purposes.60 In a manner of speaking, a nation which purports to exercise any rights to a given distance in the sea may be said to have a maritime boundary at that distance. But such a boundary, even if it delimits territorial waters, confers rights more limited than a land boundary. It is only in a very special sense, therefore, that the foreign policy of this country respecting the limit of territorial waters results in the establishment of a 'national boundary.' The power to admit new States resides in Congress. The President, on the other hand, is the constitutional representative of the United States in its dealings with foreign nations. From the former springs the power to establish state boundaries; from the latter comes the power to determine how far this country will claim territorial rights in the marginal sea as against other nations. Any such determination is, of course, binding on the States. The exercise of Congress' power to admit new States, while it may have international consequences, also entails consequences as between Nation and State. We need not decide whether action by Congress fixing a State's territorial boundary more than three miles beyond its coast constitutes an overriding determination that the State, and therefore this country, are to claim that much territory against foreign nations. It is sufficient for present purposes to note that there is no question of Congress' power to fix state land and water boundaries as a domestic matter. Such a boundary, fully effective as between Nation and State, undoubtedly circumscribes the extent of navigable inland waters and underlying lands owned by the State under the Pollard rule. Were that rule applicable also to the marginal sea—the premise on which Congress proceeded in enacting the Submerged Lands Act—it is clear that such a boundary would be similarly effective to circumscribe the extent of submerged lands beyond low-water mark, and within the limits of the Continental Shelf, owned by the State. For, as the Government readily concedes, the right to exercise jurisdiction and control over the seabed and subsoil of the Continental Shelf is not internationally restricted by the limit of territorial waters.

We conclude that, consonant with the purpose of Congress to grant to the States subject to the three-league limitation, the lands they would have owned had the Pollard rule been held applicable to the marginal sea, a state territorial boundary beyond three miles is established for purposes of the Submerged Lands Act by Congressional action so fixing it, irrespective of the limit of territorial waters. We turn now to the task of ascertaining what boundary was was so fixed for each of the defendant States.

The Particular Claims of Texas.

Texas, the only one of the defendant States which had the status of an independent nation immediately prior to its admission, contends that it had a three-league maritime boundary which 'existed at the time (it) became a member of the Union' in 1845. Whether that is so for the purposes of the Submerged Lands Act depends upon a proper construction of the Congressional action admitting the State to the Union.

Texas declared its independence from Mexico on March 2, 1836, 1 Laws, Republic of Texas, 3—7, Vernon's Ann.St.Const. and on December 19, 1836, the Texan Congress passed an Act to define its boundaries, which were described in part as

'beginning at the mouth of the Sabine river, and running west along the Gulf of Mexico three leagues from land, to the mouth of the Rio Grande, thence up the principal stream of said river. * * *' Id., 133. (Emphasis added.) See diagram at 363 U.S. 65, 80 S.Ct. 998.61

In March 1837 this country recognized the Republic of Texas.62 On April 25, 1838, the United States entered into a convention with the Republic to establish a boundary between the two countries and to provide for a survey of part of it.63 On April 12, 1844, President Tyler concluded a Treaty of Annexation with the Republic, but on June 8, 1844, the Senate refused to retify it.64 On March 1, 1845, President Tyler signed a Joint Resolution of Congress for the annexation of Texas, which provided:

'That Congress doth consent that the territory properly included within, and rightfully belonging to the Republic of Texas, may be erected into a new State, to be called the State of Texas * * *. Said State to be formed, subject to the adjustment by this government of all questions of boundary that may arise with other governments * * *.'65 (Emphasis added.)

Pursuant to this Resolution, the people of Texas adopted a constitution, Const. 1845, Vernon's Ann.St., which was submitted to Congress, and by Joint Resolution of December 29, 1845, Texas was admitted to the Union in accordance with the terms of the previous Joint Resolution.66 The 1836 Texas Boundary Act remained in force up to the time of admission, and the State Constitution expressly continued in force from that time forward all laws of the Republic not repugnant to the Federal or State Constitution or the Joint Resolution of Annexation.67

The Government, while conceding that Texas continuously asserted by statute a three-league seaward boundary, contends that at no time before, during, or after admission did the United States or any other country recognize the validity of that boundary. It follows, therefore, the Government says, that since Texas upon entering the Union became subject to the foreign policy of the United States with respect to the 'three-mile limit,' the State's seaward boundary became immediately and automatically fixed at three miles. Texas, on the other hand, argues that it effectively established, and that the United States repeatedly recognized, the State's three-league boundary before, during, and after admission, and that therefore such a boundary existed 'at the time' of its admission within the meaning of the Submerged Lands Act. For reasons already discussed, 363 U.S. at pages 24—36, 80 S.Ct. at pages 976—982, we consider that the only relevant inquiry is what boundary was fixed for the State of Texas by virtue of the Congressional action admitting it to the Union in accordance with the terms of the Joint Resolution of March 1, 1845. This inquiry first takes us back to some earlier history.

By the Treaty of Paris, signed April 30, 1803,68 France ceded to the United States the Louisiana Territory. The extent of the territory thus conveyed was left uncertain, the description in the Treaty referring only to a previous treaty by which France had acquired the territory from Spain, which in turn described the area only as 'the colony or province of Louisiana.'69 It was asserted by some that the territory acquired did not stop at the Sabine River the present boundary between the States of Louisiana and Texas—but extended westward to the Rio Grande so as to include Texas.70 However, by the Treaty of February 22, 1819, between the United States and Spain, the boundary line between the two countries was established at the Sabine.71 Those who had believed that the Louisiana Territory extended west of the Sabine decried this Treaty as a breach of faith by the United States in violation of the covenant in the 1803 Treaty which required the inhabitants of all the Louisiana Territory to be incorporated as soon as possible into the Union.72 Subsequently, the United States attempted unsuccessfully on several occasions to acquire the territory west of the Sabine by purchase.73

Meanwhile, Mexico had revolted from Spain, had been recognized by this country in 1822, and had proclaimed a federal constitution in 1824. Texas was made part of the compound province of Coahuila-Texas, with the indication that it would eventually be given a separate constitution as a sovereign state. After a series of difficulties with the central government, however, Texas in 1836 proclaimed its own independence from Mexico. It immediately sent diplomatic representatives to the United States to negotiate for annexation, but nothing was consummated at that time.74 Shortly thereafter, it promulgated the 1836 boundary statute referred to above.

It was against this background that President Tyler negotiated and sent to the Senate the 1844 Treaty for the annexation of Texas. That document provided:

'The Republic of Texas * * * cedes to the United States all its territories, to be held by them in full property and sovereignty * * *.'75

One of the objections made to the Treaty on the floor of the Senate was that it purported to cede to the United States all the territory claimed by Texas under her 1836 Boundary Act, to large parts of which Texas allegedly had no title, those parts assertedly having always been under the domination and control of Spain and Mexico.76 This objection was countered by several proponents of the Treaty who insisted that since it contained no delineation of boundaries and since the Republic of Texas was referred to by a general designation, the clause 'all its territories' ceded only that which properly and rightfully belonged to Texas, its Boundary Act notwithstanding.77

The proponents pointed also to a letter of instructions written by Secretary of State Calhoun to the United States Charge d'Affaires in Mexico a week after the Treaty was signed, which enjoined the latter, in making the Treaty known to Mexico, 'to assure the Mexican Government that it is his (the President's) desire to settle all questions between the two countries which may grow out of this treaty, or any other cause, on the most liberal and satisfactory terms, including that of boundary * * *. (The United States) has taken every precaution to make the terms of the treaty as little objectionable to Mexico as possible; and, among others, has left the boundary of Texas without specification, so that what the line of boundary should be might be an open question, to be fairly and fully discussed and settled according to the rights of each, and the mutual interest and security of the two countries.'78

Despite these controversial aspects of the Treaty, it is quite apparent that its supporters desired to press Texas' boundary claims to the utmost degree possible. President Tyler, in response to the Senate's request, transmitted to it a map showing the western and southwestern boundaries of Texas, and according generally with the Texas Boundary Act.79 Senator Walker of Mississippi, while insisting that the Treaty ceded 'only * * * the country embraced within its (Texas') lawful boundaries,' asserted that in fact her lawful boundary extended to the Rio Grande, that it had extended that far when she was ceded away by the United States in 1819, that the United States had acquiesced in those boundaries when it recognized Texas in 1837, and that Mexico had never protested the Convention of 1838 which allegedly validated that boundary.80 Senator Breese of Illinois, while assuring the Treaty's opponents that the boundary was left open to future determination, avowed that the United States had acknowledged the Texas boundaries as asserted in her 1836 statute, and that he was in favor of the recovery not only of the old province of Texas as it existed in 1803 and 1819, but also 'for as much more as the 'republic' of Texas can lawfully claim.'81 Senators Woodbury of New Hampshire and Buchanan of Pennsylvania, while expressing doubt about the validity of the Texas Boundary Act to the extent that it claimed portions of New Mexico, thought it was valid so far as it pressed beyond the Nueces to the Rio Grande and ought to be maintained.82

After the failure of the Treaty, which would have annexed Texas as a territory of the United States, several proposals were introduced in the next session of Congress for the annexation of Texas by a Joint Resolution admitting it immediately as a State.83 The doubts which had been raised in 1844 as to the validity of certain Texan pretensions to territory on her western and southwestern frontiers were reiterated during consideration of the various Resolutions, and reference was made to the fact that the rejected Treaty had been assailed as purporting to embrace such territory.84 In 1844, supporters of the Treaty had considered the general designation 'all its territories' as ceding only territory which rightfully, properly, or lawfully belonged to Texas, and as leaving to the Executive the duty of settling the extent of that territory by amicable negotiation.85 The two clauses of the 1845 Annexation Resolution (363 U.S. 37, 80 S.Ct. 983), appear, against this background, to be an express formulation of precisely the same thing. The first makes it clear that the grant is of initially undefined scope, governed by the truism that only 'the territory properly included within, and rightfully belonging to the Republic of Texas' is ceded. The second expressly contemplates future negotiation to settle the exact extent of such territory, by making it 'subject to the adjustment by this government of all questions of boundary that may arise with other governments.' In short, it is clear that the 'properly' and 'rightfully' clause was intended neither as a legislative determination that the entire area claimed by Texas was legitimately hers, nor to serve, independently of the 'adjustment' clause, as a self-operating standard for measuring Texas' boundaries. Rather, the precise fixation of the new State's boundaries was left to future negotiations with Mexico.

The circumstances surrounding the Resolution's passage make it clear that this was the understanding of Congress. Congressional attention was focused primarily on the great political questions attending annexation—primarily the extent to which slavery would be permitted in the new territory and the possibility that annexation would embroil this country with Mexico and the matter of boundary received little consideration except as it was related to the larger issues. Public agitation over annexation had become so great that some bills had proposed annexation virtually in the abstract, with all details to be worked out later.86 Although the Resolution as ultimately passed did settle the details of certain matters—notably slavery, the Texan debt, and the mode of annexation—the manifest purport of it and all the many other annexation bills introduced was to postpone the fixing of boundaries for the sake of achieving immediate annexation, and no apparent importance was attached to the particular verbal formula used to achieve such postponement.87 The general tenor of opposition to annexation changed from a fear that the cession covered too much to criticisms of the indefinite treatment of boundary and concern over whether Texas really owned as much as some supporters asserted.88 It is true that isolated statements were made which seem to indicate that the speaker thought the Resolutions would admit Texas with the boundary defined in her 1836 boundary statute, subject to possible subsequent readjustment.89 However, read in context, these statements may have meant no more than that the United States, in its negotiations with Mexico, would attempt to sustain the full extent of Texas' declared boundaries, rather than that those boundaries were in fact proper. Be that as it may, in view of the overwhelming evidence of Congressional understanding and of the express language of the Annexation Resolution as ultimately passed, the conclusion is inescapable that Texas at least as to its land area, was admitted with undefined boundaries subject to later settlement.

While this conclusion appears unavoidable as regards Texas' land boundaries, a question does exist as to whether it applies also to the State's seaward boundary. For we are unable to find in the Congressional debates either on the 1844 Treaty or the 1845 Annexation Resolution a single instance of significant advertence to the problem of seaward boundaries. Furthermore, a series of other events manifests a total lack of concern with the problem. Prior to Texan independence, the United States had entered into successive treaties with Spain and Mexico,90 which provided that

'The boundary line between the two countries, west of the Mississippi, shall begin on the Gulph of Mexico, at the mouth of the river Sabin, in the sea, continuing north, along the western bank of that river * * *.' (Emphasis added.) Just after Texas had proclaimed its independence from Mexico, the two countries, on May 14, 1836, concluded 'Articles of Agreement and Solemn Compact,' acknowledging Texan independence and setting its boundary as follows:

'The line shall commence at the estuary or mouth of the Rio Grande, on the western bank thereof, and shall pursue the same bank up the said river * * *.'91 (Emphasis added.)

Thereafter a minister was sent to the United States to seek recognition and broach the subject of annexation. With respect to the latter, he was instructed on November 18, 1836:

'As regards the boundaries of Texas * * * (w)e claim and consider that we have possession to the Rio Bravo del Norte. Taking this as the basis, the boundary of Texas would be as follows. Beginning at the mouth of said River on the Gulf of Mexico, thence up the middle thereof * * *.'92 (Emphasis added.)

Yet a month later, on December 19, 1836, the Texan Congress passed the Boundary Act which inexplicably, so far as we can find, provided that the boundary should run along the Gulf of Mexico at three leagues from land.93 Quite in contrast, in the subsequent Convention of 1838 to establish the boundary between the United States and Texas, Texas reaffirmed the 1819 and 1828 Treaties with Spain and Mexico regarding that boundary and agreed to the running and marking of

'that portion of the said boundary which extends from the mouth of the Sabine, where that river enters the Gulph of Mexico, to the Red river.'94 (Emphasis added.)

Again, as previously mentioned (note 79, 363 U.S. 41, 80 S.Ct. 985), during its consideration of the unratified Treaty of April 12, 1844, the Senate requested President Tyler to transmit any information he possessed concerning the southern, southwestern, and western boundaries of Texas. On April 26, 1844, he sent a map and a memoir by its compiler. The memoir flagrantly misquoted the 1836 Boundary Act by describing the Texas boundary as "Beginning at the mouth of the Rio Grande, thence up the principal stream of said river * * *."95

The foregoing circumstances make it abundantly plain that at the time Texas was admitted to the Union, its seaward boundary, though expressly claimed at three leagues in the 1836 Texas Boundary Act, had not been the subject of any specific concern in the train of events leading to annexation.

Given this state of affairs, we must initially dispose of an argument made by Texas. The State urges, in effect, that whether or not its maritime boundary was actually considered by the Congress or the Executive during the course of the annexation proceedings, it was incumbent upon the United States to protest or reject in some manner Texas' claim in this regard, and that failure to do so constituted in law a validation or ratification of that boundary claim upon admission. Whatever the merit of this proposition may be in the abstract, the controlling factor for purposes of this case must be the terms of the Joint Resolution of Annexation. There is, indeed, a strong argument that the 'properly,' 'rightfully,' and 'adjustment' clauses of that Resolution should be read as applying only to the land boundaries disputed with Mexico, which give rise to those qualifications, and that the Resolution was meant to validate any boundary asserted by Texas without protest. However, in light of the fact that the language employed in the Resolution is of general applicability, we should hesitate to limit its effect by reading into it such an additional unexpressed test respecting the extent of Texas' boundaries. We think that its language must be taken as applying to Texas' maritime boundary as well as to its land boundary.

On this basis an argument of the Government must now be met. It is contended that since Texas was admitted to the Union with its maritime boundary not yet settled, United States foreign policy on the extent of territorial waters, to which Texas was admittedly subject from the moment of admission, automatically upon admission operated to fix its seaward boundary at three miles. This contention must be rejected. As we have noted, the boundaries contemplated by the Submerged Lands Act are those fixed by virtue of Congressional power to admit new States and to define the extent of their territory, not by virtue of the Executive power to determine this country's obligations via-a -vis foreign nations. 363 U.S. at pages 30—36, 80 S.Ct. at pages 979—982. It may indeed be that the Executive, in the exercise of its power, can limit the enjoyment of certain incidents of a Congressionally conferred boundary, but it does not fix that boundary. If, as in the case of Texas, Congress employs an uncertain standard in fixing a State's boundaries, we must nevertheless endeavor to apply that standard to the historical events surrounding admission.

We are brought back, then, to a twofold inquiry: First, whether the three-league maritime boundary asserted by the Republic of Texas embraced an area which was 'properly included within, and rightfully belonging to' the Republic. Second, whether such a boundary was ever fixed for the State of Texas pursuant to the power reserved by Congress to adjust 'all questions of boundary that may arise with other governments.' As we have observed, it is evident that the first clause, independently of the second, was not intended to operate as a self-executing standard for determining the disputed western and southwestern boundaries of Texas. To attempt to apply that clause as fixing the extent of Texas' maritime boundary, immediately upon admission to the Union, no less than in so fixing its land boundaries, would be illusory at best. The parties devote considerable discussion to the validity or invalidity of the asserted three-league maritime boundary under international law. It is true that the propriety of a nation's seaward boundary must be viewed in the context of its obligations vis-a -vis the family of nations. But surely the Joint Resolution of Annexation could not have been meant to import such an elusive inquiry into the determination of Texas' maritime boundary, especially when that question was never even considered and when the Resolution was expressly drawn to leave undefined the land boundaries which did receive consideration. And we are unable to say that Congress might have deemed the three-league maritime boundary 'proper' or 'rightful' in some other sense. It is necessary, therefore, to look to other events to ascertain where the Texan maritime boundary was fixed pursuant to the Joint Resolution of Annexation.

Congress' failure to carry into the Annexation Resolution the boundaries fixed by the 1836 Texas Boundary Act did not, of course, foreclose the possibility that the State's boundary might ultimately be fixed in accordance with that statute. It is significant in this regard to note the opinions ventured in Congress on the probable settlement of the boundary with Mexico which would occur subsequent to annexation. One group asserted that the Texan claims to the Rio Grande, particularly the portion which encompassed New Mexico, could not possibly be maintained.96 But such remarks were made primarily by opponents of annexation and were intended as warnings against assuming that enough land would be included in the cession to pay the Texan debt or to form free States. Much more significant than opinions as to where the boundary might ultimately be fixed are observations made regarding the basis on which the boundary question might be pressed against Mexico. Supporters and opponents alike acknowledged that the United States would probably negotiate on the basis of the Texan boundaries as declared in her own boundary statute, even though some parts of that boundary might not be maintainable. Some thought this was so because those boundaries were in fact her proper and rightful boundaries.97 Others thought it was so because the United States, having acquiesced in the Boundary Act after receiving notice of it, was bound, upon admitting Texas to the Union, to maintain those claims on her behalf.98 Whatever the reasons given, it is clear that Congress, although it purposely refused to settle the question, anticipated that the Texas Boundary Act should and would be insisted on to the greatest degree possible in negotiations with Mexico.

This prediction was borne out by subsequent events. After the Annexation Resolution had been passed the transmitted to Texas for its assent, the Mexican army threatened to cross the Rio Grande and invade Texas. On June 15, 1845, President Polk wrote an informal and confidential letter to the United States Charge d'Affairs in Texas which indicated that Polk intended to repel such an invasion and to maintain the Texan claim at least to the lower portion of the Rio Grande:

'In the contingency * * * that a Mexican army should cross the Rio Grande * * * then in my judgment, —the public necessity for our interposition—will be such, that we should not stand—quietly by—and permit—an invading foreign enemy—either to occupy or devastate any portion of the Texian territory. Of course I would maintain the Texan title to the extent which she claims it to be, and not permit an invading enemy—to occupy a foot of the soil East of the Rio Grande.' Andrew Donelson Papers (Library of Congress), Vol. 10, folios 2068—2070.

Nine days before, Polk had manifested a similar intention in a letter to Sam Houston, former President of the Republic of Texas and an influential spokesman for annexation:

'You may have no apprehensions in regard to your boundary. Texas once a part of the Union and we will maintain all your rights of territory and will not suffer them to be sacrificed.' Polk Papers (Library of Congress) (1845), Vol. 84.

The attitude of the Executive at this time toward the Texan boundary is made even more explicit by an account of an interview between the United States Charge d'Affaires in Texas and Sam Houston, written by the former to his superior, the Secretary of State:

'I stated at large the general policy of the United States as justifying no doubt of the tenacity with which they would maintain not only the present claim of Texas, but reenforce it with the preexisting one derived from France in 1803 * * *

'I brought also to his view the fact that this latter feature of the proposals did not interfere with the right of Texas to define her limits as she claimed them, in her statutes—that the specification of the Rio Grande as the western boundary would be proper enough as shewing the extent to which the United States would maintain her claim as far as it could be done without manifest injustice to Mexico, and to the portion of the inhabitants of Mexico that had never yet acknowledged the jurisdiction of Texas—that practically the United States would take the place of Texas, and would be obligated to do all, in this respect, that Texas could do, were she to remain a separate nation.'99

After Texas consented to annexation and Congress had finally admitted her to statehood, the Mexican army crossed the Rio Grande and declared war upon the United States. On May 11, 1846, President Polk called on Congress to declare war against Mexico. He said in part:

'Texas, by the final action of our Congress, had become an integral part of our Union. The Congress of Texas, by its act of December 19, 1836, had declared the Rio del Norte to be the boundary of that republic. Its jurisdiction had been extended and exercised beyond the Nueces. The country between that river and the Del Norte had been represented in the congress and in the convention of Texas; had thus taken part in the act of annexation itself; and is now included within one of our congressional districts. Our own Congress had, moreover, with great unanimity, by the act approved December 31, 1845, recognized the country beyond the Nueces as a part of our territory, by including it within our own revenue system; and a revenue officer, to reside within that district, has been appointed, by and with the advice and consent of the Senate. It became, therefore, of urgent necessity to provide for the defence of that portion of our country.' H.R.Exec.Doc. No. 60, 30th Cong., 1st Sess. 4, 7.

In a later message to Congress on December 8, 1846, Polk manifested the same disposition, H.R.Exec.Doc. No. 4, 29th Cong., 2d Sess. 13—14. And on December 7, 1847, he explained that the United States had rejected a treaty proposal by Mexico because

'It required the United States to dismember Texas, by surrendering to Mexico that part of the territory of that State lying between the Nueces and the Rio Grande, included within her limits by her laws when she was an independent republic, and when she was annexed to the United States and admitted by Congress as one of the States of our Union.' H.R.Exec.Doc. No. 8, 30th Cong., 1st Sess. 9.

However, there is absolutely nothing to indicate that the Executive, any more than the Congress, was interested in, or was at all aware of any problem presented by, the seaward boundary of Texas claimed in its 1836 Boundary Act. The Government urges, by way of explanation, that the United States had, by this time, firmly established a policy of claiming no more than three miles of territorial waters. But the Executive's responsibility for fixing the Texan boundary derived from a delegation of Congressional power to admit new States, not from the Executive's own power to fix the extent of territorial waters. As we have already pointed out, the two powers can operate independently, and only the first is determinative in this case. To the extent it may be argued that the Executive would naturally take account of its own policy toward territorial waters in fixing the Congressionally mandated boundary, the data presented to us are utterly devoid of any suggestion that such was the case. On the contrary, it is evident that the overwhelming concern of the President and his subordinates was to maintain to the greatest extent possible the land boundaries claimed by Texas and disputed with Mexico, as anticipated by Congress. The settlement of that matter remained for future events, to which we now turn.

On April 15, 1847, Nicholas P. Trist was appointed Commissioner to Mexico to negotiate a peace treaty. Among his instructions was a project of the proposed treaty, which provided:

'The boundary line between the two Republics shall commence in the Gulf of Mexico three leagues from land opposite the mouth of the Rio Grande, from thence up the middle of that river * * *.' 5 Miller, Treaties and Other International Acts of the United States of America (1937), 265. (Emphasis added.)

This language was incorporated verbatim into Article V of the Treaty of Guadalupe Hidalgo as finally signed on February 2, 1848, 9 Stat. 922, which fixed the boundary between the United States and Mexico from the Gulf of Mexico to the Pacific coast.100 While there was considerable disagreement in the negotiations over the various land boundaries, the proposals of both parties never departed from the three-league provision. See 5 Miller, op. cit. supra, at 270, 288, 289, 315, 317, 325.

Tirst stated in his notes that one object of instructions given to his predecessor, substantially identical in relevant part to those given him, was to get Mexico to agree to a boundary which

'would throw within the territory of the United States the country lying east of the Rio Grande. Or, as said object stands in said instructions, specifically stated & expressed, it was the object of prevailing upon Mexico 'to agree that the line shall be established along the boundary defined by the act of Congress of Texas, approved December 19, 1836, to wit: beginning at 'the mouth of the Rio Grande; thence up the principal stream of said river * * *.'"101

While this misquotation of the Texas Boundary Act again demonstrates total insensitivity to any problem of a seaward boundary, the passage does indicate that the United States was attempting to follow the Texas statute in negotiating the boundary.102 More important for the purposes of this case are the circumstances that the three-league provision was made an express part of the Treaty of Guadalupe-Hidalgo, that such boundary was reaffirmed five years later in the Gadsden Treaty of December 30, 1853103 and subsequently in a long line of international conventions,104 and that it has never been repudiated.

The Treaty unquestionably established the Rio Grande from New Mexico to the Gulf as the land boundary not only of the United States but also of Texas, since the Executive, acting pursuant to the power given by Congress to 'adjust' Texas' boundaries in dealings with other nations, pressed that boundary against Mexico on the theory that it embraced territory rightfully belonging to the State of Texas. There is nothing to indicate that the extension of that boundary three leagues into the Gulf, pursuant to the very same Boundary Act, was treated on any different basis. The portion of the boundary extending into the Gulf, like the rest of the line, was intended to separate the territory of the two countries, and to recognize that the maritime territory of Texas extended three leagues seaward.

Whether the Treaty be deemed to constitute an exercise of the power to adjust the boundaries left unsettled by the 1845 Joint Resolution of Annexation, or a post hoc recognition of a seaward boundary which was actually fixed for Texas upon its admission in 1845, or a fixation of boundaries which related back to the time of admission, is of no moment. Although the Submerged Lands Act requires that a State's boundary in excess of three miles must have existed 'at the time' of its admission, that phrase was intended, in substance, to define a State's present boundaries by reference to the events surrounding its admission. As such, it clearly includes a boundary which was fixed pursuant to a Congressional mandate establishing the terms of the State's admission, even though the final execution of that mandate occurred a short time subsequent to admission.

The Government contends that the Treaty of Guadalupe Hidalgo is of no significance in this case because the line drawn three leagues out to sea was not meant to separate territory of the two countries, but only to separate their rights to exercise certain types of 'extraterritorial' jurisdiction with respect to customs and smuggling. We believe the conclusion is clear that what the line, denominated a 'boundary' in the Treaty itself, separates is territory of the respective countries. No reference to 'extraterritorial' jurisdiction is made in the Treaty, and no such concept can be gleaned from the context of the negotiations. Being based on the three-league provision of the 1836 Texas Boundary Act, which itself denotes a territorial boundary, the obvious and common-sense meaning of the analogous treaty provision is that it separates the maritime territory of the United States and Mexico.

The Government relies on certain diplomatic correspondence as evidencing a subsequent construction of the Treaty contrary to this conclusion. In 1848, when Great Britain protested the three-league provision of the Treaty, both the United States and Mexico replied that the Treaty defined rights only as between the two countries and was not intended to impair the rights of any other nation in the marginal sea.105 In 1875, Secretary of State Hamilton Fish made a similar explanation to Lord Derby of England, but added a new contention that the boundary provision was 'probably' suggested by the Acts of Congress permitting revenue officials to board vessels bound for the United States within four leagues of the coast.106 And in 1936, after Mexico had asserted a three-league belt of territorial water along its entire coast, the United States, in denying that the Treaty gave Mexico such a right, adopted both rationales relied on in 1875, and in addition contended that the boundary provision did recognize the territory of the two countries as extending three leagues from the coast, but only in the 'one area' adjacent to the international boundary.107 It seems evident from the shifting and uncertain grounds upon which these pronouncements relied that they should be taken as reflecting no more than after-the-fact attempts to limit the effect of a provision which patently purported to establish a three-league territorial boundary, so as to bring it into accord with this country's international obligations. Undoubtedly the Executive has the right to limit the effect to be accorded a treaty provision in its dealings with other countries. But where, as here, that Treaty touches upon relationships between the Nation and a State created pursuant to a Congressional mandate, the original purport of the Treaty must control, and the dealings of the Executive with other nations cannot affect the State's rights in any way as a domestic matter.

We conclude, therefore, that pursuant to the Annexation Resolution of 1845, Texas' maritime boundary was established at three leagues from its coast for domestic purposes. Of course, we intimate no view on the effectiveness of this boundary as against other nations. Accordingly, Texas is entitled to a grant of three leagues from her coast under the Submerged Lands Act.

Louisiana's claims, like those of Texas, are based on the contention that it had a three-league maritime boundary which existed "at the time" it was admitted to the Union, and must be judged by the same standards. The Act of Congress admitting the State to the Union in 1812107a described the new State's boundaries as follows:

"beginning at the mouth of the river Sabine; thence, by a line to be drawn along the middle of said river, including all islands to the thirty-second degree of latitude; thence, due north, to the northernmost part of the thirty-third degree of north latitude; thence, along the said parallel of latitude, to the river Mississippi; thence, down the said river, to the river Iberville; and from thence, along the middle of the said river, and lakes Maurepas and Ponchartrain, to the gulf of Mexico; thence, bounded by the said gulf, to the place of beginning, including all islands within three leagues of the coast...." (Emphasis added.)

Louisiana claims that the concluding clause "including all islands within three leagues of the coast" should be read to mean that Congress fixed as the State's seaward boundary a line three leagues from its coast, and that such a reading is supported both by the State's preadmission history and by subsequent events. The Government, on the other hand, insists that the phrase includes only the islands themselves lying within three leagues of the coast, and not all water within that distance as well.108

The language of the Act itself appears clearly to support the Government's position. The boundary line is drawn down the middle of the river Iberville 'to the gulf of Mexico,' not into it for any distance. The State is thence to be bounded 'by the said gulf,' not by a line located three leagues out in the Gulf, 'to the place of beginning,' which is described as 'at the mouth of the river Sabine,' not somewhere beyond the mouth in the Gulf. (Emphasis added.) And while 'all islands' within three leagues of the coast were to be included, there is no suggestion that all waters within three leagues were to be embraced as well. In short, the language of the Act evidently contemplated no territorial sea whatever.

Similar language was employed in the Treaty of Paris of September 3, 1783, by which Great Britain recognized the independence of the United States.109 After describing the boundary of the United States from the mouth of the St. Croix River in the Bay of Fundy to the mouth of the St. Mary's River between Georgia and Florida, the parties added: 'comprehending all islands within twenty leagues of any part of the shores of the United States * * *.' In the light of Jefferson's observation, only 10 years later, that national claims to control of the sea beyond approximately 20 miles from the coast had not therefore been generally recognized among maritime powers;110 his accompanying proposal that a three-mile limit should be placed upon the extent of territorial waters;111 and subsequent American and British policy in this regard, see note 54, supra, it is hardly conceivable that this provision of the Treaty was intended to establish United States territorial jurisdiction over all waters lying within 20 leagues (60 miles) of the shore.112 No reason appears for reading the Louisiana statute differently. The conclusion that language claiming all islands within a certain distance of the coast is not meant to claim all the marginal sea to that distance is further confirmed by the Act defining the boundaries of Georgia,113 which claims three miles of marginal sea but all islands within 20 leagues of the coast. That Act provides:

'along the middle of (the St. Mary's) river to the Atlantic Ocean, and extending therein three English miles from low-water mark; thence running in a northeasterly direction and following the direction of the Atlantic coast to a point opposite the mouth, or inlet, of said Savannah River; and from thence to the mouth or inlet of said Savannah River, to the place of beginning; including all the lands, waters, islands, and jurisdictional rights within said limits, and also all the islands within 20 marine leagues of the seacoast.'

Nothing in the case of Alaska Pacific Fisheries v. United States, 248 U.S. 78, 39 S.Ct. 40, 63 L.Ed. 138, tends toward a contrary construction. The Court there held that an Act of Congress designating as an Indian reservation 'the body of lands known as Annette Islands' included the intervening and surrounding waters and submerged lands, which were inland waters admittedly under the control of the United States, whether actually part of the reservation or not. The Court, construing the statute in light of the Indians' historic use of these waters as fishing grounds, merely concluded that Congress intended to include in the area reserved the waters and water bed, as well as the islands, referring to both 'as a single body of lands.' Id., 248 U.S. 89, 39 S.Ct. 42. The construction here contended for by Louisiana would, in contrast, sweep within the State's jurisdiction waters and submerged lands which bear no proximate relation to any islands, and which would otherwise be part of the high seas.

Louisiana also contends, relying on United States v. State of Texas, 162 U.S. 1, 16 S.Ct. 725, 40 L.Ed. 867; State of Louisiana v. State of Mississippi, 202 U.S. 1, 26 S.Ct. 408, 50 L.Ed. 913, that this Court has already determined that its boundary includes three leagues of marginal sea. The Texas case, however, involved only the question whether Greer County, in the northwest part of the State, was properly a part of Texas. And even if that case had effectively established a three-league maritime boundary for Texas, which quite evidently it did not, that would not establish a similar boundary for Louisiana.

The Mississippi case involved only the issue of the boundary between Louisiana and Mississippi. Louisiana relies on the holding of the Court that because the eastern boundary of Louisiana was a water boundary along the middle of the river Iberville, extending to the Gulf, it went on to include a deep-water sailing channel in the Gulf adjacent to Mississippi. It also relies on a rough map included in the Court's opinion showing a line drawn all the way around the State's coast at some distance in the Gulf. There is, however, no indication whatever that the line so indicated bore any relation to the three-league provision in the Louisiana Act of Admission. Furthermore, if there could be any doubt that only the portion of the water boundary adjacent to Mississippi was considered by the Court, it is dispelled by the Court's statement that

'Questions as to the breadth of the maritime belt or the extent of the sway of the riparian states require no special consideration here. The facts render such discussion unnecessary.' Id., 202 U.S. 52, 26 S.Ct. 422.

See also United States v. State of California, supra, 332 U.S. at page 37, 67 S.Ct. at page 1667.

Preliminarily, it should be observed that in light of what has already been said, 363 U.S. at pages 24—30, 80 S.Ct. at pages 976—979, Louisiana's preadmission history is relevant in this case only to the extent that it aids in construing the Louisiana Act of Admission. The thrust of the State's argument on this score is that the boundaries fixed by the Act of Admission comprised the entire area acquired by the United States from France through the Louisiana Purchase, effected by the Treaty of Paris in 1803; that the extent of this area traces back, through cessions by France to Spain in 1762 and Spain to France in 1800, to what was first claimed by France in 1682; and that such area originally extended some 120 miles into the Gulf of Mexico, and in any case, by virtue of other events, at least three leagues into the Gulf.

For reasons now to be discussed we think that this historical thesis is not borne out by any of the documents or events on which Louisiana relies, but that to the contrary what has been shown us leads to the conclusion that Louisiana's preadmission territory, consistently with the Act of Admission, stopped at its coast and did not embrace any marginal sea.

1. The area which includes the present State of Louisiana was first claimed for France by La Salle in 1682, extending southward

'as far as (the Mississippi's) * * * mouth in the sea, or gulf of Mexico, about the twenty-seventh degree of the elevation of the North Pole * * *.'114

It is apparent from the face of La Salle's proclamation that it was the mouth of the Mississippi which defined the southerly limit of his claim. His expression of belief that the river mouth was at 'about' the 27th parallel does not indicate an intent to claim to that parallel, which is in fact some 120 miles south of the Mississippi's mouth. In any event, the proce s-verbal of Jacques de la Me tairie, notary of the La Salle expedition,115 shows that the proclamation was issued after the mouth of the Mississippi had been reached and the party had returned upstream only far enough to find solid ground for the erection of a monument, and that La Salle then thought, mistakenly in fact, that they were at about the 27th parallel. Other documents also indicate that the river mouth defined the extent of the claim and that the territory included no marginal sea whatever.116

2. By a secret Treaty executed at Fontainebleau on November 3, 1762, France ceded to Spain 'all the country known under the name of Louisiana, as well as New Orleans and the island in which the place stands.'117 By the secret Treaty of San Ildefonso, signed October 1, 1800, Spain retroceded the 'colony and province of Louisiana' to France.118 Certainly there is nothing on the face of either of these Treaties to indicate that France or Spain claimed any territorial sea.

3. Louisiana argues, however, that certain treaties between France, Spain, and other nations evidence such an intent. Four of these treaties concern the right of the French to fish within certain distances of the coasts of the British possessions in North America, varying from three to 30 leagues. The relevant portions do not relate to French or Spanish territory at all.119 In another, Great Britain undertook not to permit its subjects to navigate or fish within 10 leagues of coasts occupied by Spain 'in the Pacific Ocean, or in the South Seas,' so as to prevent illicit trade with Spanish settlements.120 The Treaty does not relate to the area in question, and, far from being an assertion of a territorial claim by Spain, imposed an obligation of a limited nature on Great Britain alone. The same reasoning applies to another of these treaties, the Treaty between Spain and Tripoli, signed September 10, 1794, prohibiting the capture of any vessel within 10 leagues from coasts of the dominions of Spain.121 Reliance is also placed on an ordinance promulgated by Philip II of Spain in October 1565, asserting rights within the visual horizon of the coasts of Spain and its possessions.122 It may be questioned whether this ordinance even constituted an assertion of territorial jurisdiction as it is known today, especially in view of the fact that the concept of the territorial sea did not arise in international law until after this country achieved its independence. See United States v. State of California, supra, 332 U.S. 32—33, 67 S.Ct. 1665. Even if it did, the ordinance can hardly be taken as applying to a territory not acquired by Spain until 200 years later or as affecting the construction of the Act admitting Louisiana to the Union 250 years later.123

4. By the Treaty of Paris, signed April 30, 1803, France ceded to the United States the Louisiana Territory with all its rights and appurtenances 'as fully and in the same manner as they have been acquired by the French Republic, in virtue of the above-mentioned treaty (Treaty of San Ildefonso, Oct. 1, 1800), concluded with his Catholic Majesty,' including 'the adjacent islands belonging to Louisiana.'124 To show that the Act admitting Louisiana to the Union must be construed as referring to the Union must Treaty, Louisiana relies on Article III of the Treaty, which required the United States to admit 'the ceded territory' to statehood as soon as possible. But since the historic documents to which our attention has been called fail to show that the ceded territory included any territorial sea, taking the Treaty as defining the scope of the Act of Admission only confirms the view that Louisiana's maritime boundary was fixed at, and not somewhere in, the Gulf of Mexico.

5. Louisiana also asserts that about the time of its admission, the United States was claiming three leagues of territorial waters in the Gulf, and that the Act of Admission was framed with reference to that claim. However, from the great variety of documentation presented by the parties, the most that could possibly be said is that the United States, contrary to the Government's contention, had not unequivocally asserted the applicability of the three-mile limit in the Gulf of Mexico. Assuming, as the defendants have here argued, that it would have been reasonable under international law for the United States to claim three leagues of territorial waters in the Gulf had it so chosen, we nevertheless cannot conclude that Congress meant to define Louisiana's boundaries by reference to a rule which was the subject of so much difference among nations and which had never been adopted by this country. The terms of the Act of Admission seem to point so strongly to the contrary that it would require much more convincing evidence than this to persuade us that the construction advanced by Louisiana is correct. Furthermore, it is significant that only a few years later, Congress admitted Mississippi and Alabama to the Union, describing their boundaries as including all islands within six leagues of the shore. See 363 U.S. at pages 81, 82, 80 S.Ct. at pages 1005 and 1006. If the three-league provision in Louisiana's Act of Admission was intended to reflect a policy of claiming three leagues of territorial waters, it is difficult to understand why Congress, so shortly thereafter, should have incorporated a six-league limit in an otherwise identical provision.

3. Postadmission Events.

To the extent that Louisiana's reliance on postadmission events is for the purpose of showing that the United States established a three-league 'national boundary' in the Gulf, they cannot help her case, for reasons previously discussed. 363 U.S. at pages 30—36, 80 S.Ct. at pages 979—982. We need not decide whether the United States ever claimed three leagues of territorial waters along the entire Gulf coast, which could in a sense be said to constitute a national boundary, or whether, if it did, Louisiana would have been entitled to extend its own boundary to that distance. Under the Submerged Lands Act, Louisiana's boundary must be measured at the time of her admission, unless a subsequent change was approved by Congress. If the Act of Admission fixed the boundary at the shore, neither action by Congress fixing greater boundaries for other States nor Executive policy on the extent of territorial waters could constitute Congressional approval of a maritime boundary for Louisiana. Louisiana, however, insists that certain of these events subsequent to admission must be considered in construing the Act of Admission.

1. We are urged to infer that since, as the Court today holds, three-league boundaries were fixed for Texas (363 U.S. at page 64, 80 S.Ct. at page 996) and Florida (363 U.S. at page 121, 80 S.Ct. at page 1026), and since, after Texas' admission, the Treaty of Guadalupe Hidalgo fixed the starting point of the boundary between the United States and Mexico at three leagues in the Gulf, Congress must have meant to treat Louisiana equally. The inference must be based primarily on the existence of the Texas and Florida boundaries, for the Treaty of Guadalupe Hidalgo relates only to the boundary between Texas and Mexico, and tends to prove nothing more than the existence of a three-league boundary for Texas. In view of the fact that shortly after Louisiana's admission, Congress fixed maritime boundaries for Mississippi and Alabama which, even on Louisiana's construction, would be different than three leagues, we can discern no consistent Congressional policy toward the maritime boundaries of the Gulf States at the time of Louisiana's admission, even if the much later actions with respect to Texas and Florida could be thought to have established such a policy. Cf. State of Louisiana v. State of Mississippi, supra, 202 U.S. at page 41, 26 S.Ct. at page 418. It would require clear evidence that such a policy was operative at the time Congress passed the Act admitting Louisiana to overcome language in that Act which points so strongly against the construction urged by Louisiana. Nor does the concept of equal footing require such a construction. While the ownership of certain lands within state boundaries has been held to be an inseparable attribute of the political sovereignty guaranteed equally to all States, see United States v. State of Texas, supra, 339 U.S. at page 716, 70 S.Ct. at page 922, the geographic extent of those boundaries, and thus of the lands owned, clearly has nothing to do with political equality. A fortiori this is true in the case of maritime boundaries beyond low-water mark, since, except as granted by Congress, the States do not own the lands beneath the marginal seas. See United States v. State of California, supra; State of Alabama v. State of Texas, supra.

2. Certain treaties successively entered into from 1819 to 1838 by the United States with Spain, Mexico, and the Republic of Texas establishing the boundary between Texas and the United States are relied on as indicating that the State and Federal Governments thought that Congress had fixed a threeleague maritime boundary for Louisiana.125 Louisiana contends that the treaties fixed the beginning of the international boundary at a point three leagues from land, and that therefore the southwestern corner of Louisiana as well as the southeastern corner of Texas must have been regarded as extending seaward to that distance. Whether or not such reasoning is valid, the language of the treaties refutes the premise that the international boundary began three leagues from land. Both the 1819 and the 1828 treaties recited that '(t)he boundary line between the two countries, west of the Mississippi, shall begin on the Gulph of Mexico, at the mouth of the river Sabine, in the sea * * *.' The Treaty of 1838 referred to the Treaty of 1828, and provided for a survey of 'that portion of the said boundary which extends from the mouth of the Sabine, where that river enters the Gulph of Mexico, to the Red river.'126

3. In its answer to the original complaint, Louisiana alleged certain acts of sovereignty over the marginal sea and seabed and the acquiescence of the Federal Government therein.127 Although it has now abandoned its ear contention that these acts establish its title by prescription and estoppel apart from the Submerged Lands Act, it now urges that they indicate a subsequent practical construction of Louisiana's Act of Admission. Taking these facts as proved, they do not have the effect urged by Louisiana. They indicate only that until the 1930's, the Federal Government may have believed that lands beneath the marginal sea belonged to the States. There is no allegation that the geographical extent of Louisiana's assertions, assuming that such assertions were made beyond three miles, was drawn in question, or that the question of Louisiana's boundary was considered. Some of the acts alleged constituted police power measures which a State can enforce it has now abandoned its earlier contention Skiriotes v. State of Florida, 313 U.S. 69, 61 S.Ct. 924, 85 L.Ed. 1193. As to acts touching the development of the submerged lands themselves, the United States would have had no reason to object to activity beyond Louisiana's boundary, since not until 1945 did the Federal Government assert any rights in the Continental Shelf for itself. If any of the other acts alleged conflicted with this Nation's policy toward territorial waters, objection would have lain regardless of the location of the State's boundary, and lack of objection is therefore, for the purposes of this case, inconclusive.

4. Finally, Louisiana relies on a 1954 statute of its own establishing the State's boundary at three leagues seaward of the line between inland and open waters. Act 33 of 1954, LSA-Rev.Stat. 49:1. It is said that in so legislating Louisiana followed the coastline as defined in regulations promulgated by the Commandant of the Coast Guard, pursuant to the Federal Act of February 19, 1895, 28 Stat. 672, 33 U.S.C. § 151, 33 U.S.C.A. § 151, and that because of this, and also on considerations of convenience and certainty, this state enactment should be accepted as establishing Louisiana's coast. We think the consideration of this contention should be postponed to a later stage of this case. We decide now only that Louisiana is entitled to submerged-land rights to a distance no greater than three geographical miles from its coastlines, wherever those lines may ultimately be shown to be.

Mississippi's claim to a three-league seaward boundary must fail largely for the same reasons that have led us to reject the similar claim of Louisiana.

The territory which now comprises the part of Mississippi lying south of the 31st parallel was originally ceded by France to Great Britain by the Treaty of Paris of February 10, 1763.128 Great Britain designated this territory part of West Florida, and by proclamation of October 7, 1763, King George III described West Florida as

'bounded to the southward by the gulf of Mexico, including all islands within six leagues of the coast, from the river Apalachicola to Lake Pontchartrain * * *.'129

On September 3, 1783, Great Britain and Spain signed a treaty by which Great Britain ceded this area to Spain as part of a cession embracing all of western and eastern Florida.130

By the Treaty of San Ildefonso, signed October 1, 1800, Spain ceded to France 'the colony and province of Louisiana.' See 363 U.S. at page 72, 80 S.Ct. at page 1001. In the Treaty of Paris of April 30, 1803, France ceded Louisiana to the United States to the same extent as France had acquired it by virtue of the Treaty of San Ildefonso. See 363 U.S. at page 74, 80 S.Ct. at page 1002. A dispute arose between the United States and Spain as to whether, by the Treaty of San Ildefonso, Spain had conveyed to France any land east of the Mississippi River (including any part of West Florida), and therefore whether France could have subsequently passed that territory to the United States in the Treaty of Paris. On October 27, 1810, President Madison claimed the right to possession of the area,131 and on May 14, 1812, Congress made it part of the Mississippi Territory.132 On March 1, 1817, Congress authorized the creation of the State of Mississippi, specifically setting out its boundaries, in part as follows:

'thence due south to the Gulf of Mexico, thence westwardly, including all the islands within six leagues of the shore, to the most eastern junction of Pearl river with Lake Borgne * * *.'133 (Emphasis added.)

The Mississippi Constitution, approved by the Act admitting the State to the Union on December 10, 1817,134 contained an identical provision. Finally, by the Treaty of February 22, 1819, Spain purported to cede East and West Florida to the United States. 8 Stat. 254. It was determined, however, in Foster v. Neilson, 2 Pet. 253, 7 L.Ed. 415, that the portion of the State of Mississippi south of the 31st parallel passed to the United States as part of the Louisiana Purchase under the Treaty of Paris in 1803, and not as part of West Florida under the Spanish Treaty of 1819.

We have already held with respect to Louisiana's claim to a three-league maritime boundary that an Act of Admission which refers to all islands within a certain distance of the shore does not appear on its face to mean to establish a boundary line that distance from the shore, including all waters and submerged lands as well as all islands. There is nothing in Mississippi's history, just as there is nothing in Louisiana's, to cause us to depart from that conclusion in this instance. Indeed, Mississippi relies almost entirely on the fact that the very language which defeats its contention was repeatedly used, in the 1763 Proclamation by King George III, in the Congressional Enabling Act, and in the State Constitution, and was implicitly incorporated in mesne conveyances.

Mississippi also urges that the draftsmen of the provision must have intended to include all waters and submerged lands within six leagues from shore because the waters are very shallow and the islands are constantly shifting. This argument, however, appears only to strengthen the conclusion that it was islands upon which the provision focused, and not waters where there were no islands.

We must told that Mississippi is not entitled to rights in submerged lands lying beyond three geographical miles from its coast.135

The preadmission history of Alabama is essentially the same as that of Mississippi, the portion of the State lying south of the 31st parallel having passed by the same mesne conveyances from France to the United States. That portion was incorporated into the Mississippi Territory by the Act of May 14, 1812,136 and became a part of the State of Alabama formed out of that territory. Its Act of Admission137 incorporated the Enabling Act, which described its boundary in part as follows:

'thence due south, to the Gulf of Mexico, thence eastwardly, including all the islands within six leagues of the shore, to the Perdido river * * *.'138

The same reasons applicable to the claims of Louisiana and Mississippi compel us to hold that Alabama is not entitled to rights in submerged lands lying beyond three geographical miles from its coast.139

Conclusions.

On the basis of what has been said in this opinion, we reach the following conclusions:

1. As to the States of Louisiana, Mississippi, and Alabama, a decree will be entered (1) declaring that the United States is entitled, as against these States, to all the lands, minerals, and other natural resources underlying the Gulf of Mexico more than three geographical miles from the coast of each such State, that is, from the line of ordinary low-water mark and outer limit of inland waters, and extending seaward to the edge of the Continental Shelf; (2) declaring that none of these States is entitled to any interest in such lands, minerals, and resources; (3) enjoining these States from interfering with the rights of the United States therein; (4) directing each such State appropriately to account to the United States for all sums of money derived therefrom subsequent to June 5, 1950:140 and (5) dismissing the cross bill of the State of Alabama.141

2. As to the State of Texas, a decree will be entered (1) declaring that the State is entitled, as against the United States, to the lands, minerals, and other natural resources underlying the Gulf of Mexico to a distance of three leagues from Texas' coast, that is, from the line of ordinary low-water mark and outer limit of inland waters; (2) declaring that the United States is entitled, as against Texas, to no interest therein; (3) declaring that the United States is entitled, as against Texas, to all such lands, minerals, and resources lying beyond that area, and extending to the edge of the Continental Shelf; (4) enjoining the State from interfering with the rights of the United States therein; and (5) directing Texas appropriately to account to the United States for all sums of money derived since June 5, 1950, from the area to which the United States is declared to be entitled.

3. Jurisdiction over this case will be retained for such further proceedings as may be necessary to effectuate the rights adjudicated herein.

4. The motions of Louisiana and Mississippi to take depositions and present evidence are denied, without prejudice to their renewal in such further proceedings as may be had in connection with matters left open by this opinion.142 In so deciding we have not been unmindful of this Court's liberality in original cases of 'allowing full development of the facts.' See United States v. State of Texas, 339 U.S. 707, 715, 70 S.Ct. 918, 922, 94 L.Ed. 1221. We think, however, that the conclusions to be drawn from the historical documents relied on by Louisiana, Mississippi, and Alabama are so clear as to leave no issue presently involved open to dispute, and that we would not be justified in postponing the granting of the relief to which we find the United States entitled as against these three States.143 By the same token we see no need to postpone the adjudication of the issues now presented as between the United States and Texas, and we do not understand the Government indeed to contend otherwise.

The parties may submit an appropriate form of decree giving effect to the conclusions reached in this opinion. It is so ordered.

Decree in accordance with opinion.

The CHIEF JUSTICE and Mr. Justice CLARK took no part in the consideration or decision of these cases.

(For opinion of Mr. Justice FRANKFURTER, joined by Mr. Justice BRENNAN, Mr. Justice WHITTAKER and Mr. Justice STEWART see 363 U.S. 129, 80 S.Ct. 1030.)

Mr. Justice BLACK, concurring in part and dissenting in part.

I concur in the Court's judgment that Texas owns the belt of submerged lands extending three marine leagues from that State's coastline into the Gulf of Mexico (including oil and other resources), but dissent from denial of like claims by Louisiana, Mississippi and Alabama.

The claims of all these States depend on our interpretation and application of the Submerged Lands Act passed in 1953.1 Two bills previously passed by Congress, substantially the same as the 1953 Act, were vetoed by the President.2 After the first veto we refused to hold that California, Texas and Louisiana owned or had ever owned legal title to the submerged lands adjacent to their coasts. We held that the United States, not the States, had paramount rights in and power over such lands and their products, including oil.3 Congress accepted our holdings as declaring the then-existing law that these States had never owned the offshore lands—but believed that all coastal States were equitably entitled to keep all the submerged lands they had long treated as their own,4 without regard to technical legal ownership or boundaries. Accordingly, Congress exercised its power by passing the Submerged Lands Act in an attempt to restore the 'rights and powers of the States and those holding under (them) * * * as they existed prior to the decision of the Supreme Court of the United States in the California case.'5

To accomplish this purpose the Act first provides for an outright grant to all the coastal States of a boundary three geographical miles from their coastlines.6 The Gulf States, however, were not satisfied with three miles but claimed that special circumstances entitled them to three leagues (about 10 1/2 miles) or more. They urged, among other things, that claims of the Gulf States and their predecessors in title had always been more expansive than claims of coastal States in other parts of the country; that when admitted to the Union their constitutions contained definitions which, properly interpreted, described boundaries extending three to six leagues seaward; that the Gulf States had not only claimed these more expansive boundaries, but had always exercised possessory and ownership rights over these marginal lands and their products at will without regard to any three-mile limitations; and that historically the United States had never questioned any of their claims until disputes arose regarding oil leases during the late 1930's.7 Moved by these arguments, strongly supported by evidence and concessions, Congress did not limit its grant to the Gulf States to three miles of submerged lands, but granted a belt extending all the way to each State's 'boundaries * * * as they existed at the time such State became a member of the Union * * * but in no event * * * more than * * * three marine leagues into the Gulf of Mexico. * * *' 43 U.S.C. § 1301(b), 43 U.S.C.A. § 1301(b). We have upheld the power of Congress to convey these marginal lands to the States. State of Alabama v. State of Texas, 347 U.S. 272, 74 S.Ct. 481, 98 L.Ed. 689.

The statute neither defines the kind of 'boundary' which is to measure Congress' grants to these States, nor particularizes the criteria for deciding it. We may agree with the Government that the term 'boundary' was used here in its usual sense to mean the limit of territory, which, in the case of a coastal boundary, would mean the outer limit of the territorial sea. But this does not get us very far in determining the location of these States' boundaries. For a number of reasons I cannot accept the Government's contention that each State must show a 'legal' or 'legally accepted' boundary as of the date it became a member of the Union. I cannot see how we can be expected retroactively to reconstruct a technically defined legal boundary, extending out into the lands under the Gulf, if the States never technically owned any of these lands. In United States v. State of California, 332 U.S. 19, 67 S.Ct. 1658, 91 L.Ed. 1889, and the cases which followed it, this Court held that the States of California, Texas and Louisiana did not own or have title to the offshore lands they claimed. If we were now to hold that these States must prove technical title as of the early 1800's in order to satisfy the Submerged Lands Act and that they have succeeded in doing so, we would in effect be overruling our prior cases, cases expressly accepted by Congress as declaring the law when the 1953 Act was passed. I cannot believe that Congress intended us to try to use again the same 'legal' test of ownership we had applied in holding that the States did not own any part of their marginal lands, particularly since Congress passed the 1953 Act to allow the States' rights to be determined under established equitable, not strictly legal, principles. The opinion of Mr. Justice DOUGLAS forcefully points out the difficulty, if not the impossibility, of finding that any of these States ever had a technical legal boundary out in the ocean. Even if a technical determination of boundaries were intended by Congress, rather than attempt that impossible task, I would prefer to return the Act to Congress for a more precise expression of its will. Cf. United States v. Alcea Band of Tillamooks, 329 U.S. 40, 54, 67 S.Ct. 167, 174, 91 L.Ed. 29 (concurring opinion); Northwestern Bands of Shoshone Indians v. United States, 324 U.S. 335, 354—358, 65 S.Ct. 690, 700—702, 89 L.Ed. 985 (concurring opinion).

Moreover, the Submerged Lands Act prescribes no standards for determining a strictly 'legal' boundary according to the conveyancer's art. There are, of course, no markers out in the Gulf of Mexico to show where the boundaries were when the States were admitted. Since some were admitted anywhere from 140 to 150 years ago there are no living witnesses to testify where their boundaries were at that time. But despite these difficulties, it is our duty to give effect to the congressional act as best we can. It is therefore my view that since we cannot look to legalistic tests of title, we must look to the claims, understandings, expectations and uses of the States throughout their history. This is because of the congressional expressions, stated time and time again that the Act's purpose was to restore to the States what Congress deemed to have been their historical rights and powers. Nor can I accept the Government's argument that these States' interests in the marginal seas must be determined in accord with the national policy of foreign relations. Everything in the very extended congressional hearings and reports refutes any such idea. Instead, these sources indicate that Congress passed the Act to apply broad principles of equity—not as we see it but as Congress saw it.8 In determining the boundaries of these States, we must, I think, recognize and follow the same principles if we are to effectuate the congressional purpose that produced this Act. That is what I would do. A few references to the legislative background will illustrate the guides Congress intended we should apply in interpreting its Act.

Senator Ellender of Louisiana invoked the equitable sense of Congress.9 Senator Holland of Florida, the author of the bill, urged Congress to 'look into the equities and the moral considerations that are involved. * * *'10 The presiding officer of the Senate Committee, who conducted the hearings and reported the bill, told the Congress that 'justice, equity, and the best interests of the Nation will be served by the enactment of this legislation.'11 The Senate Committee Report on an earlier bill, printed and adopted as a part of the Report on the 1953 Act, declared that 'The Congress, in the exercise of its policy powers, is not and should not be confined to the same technical rules that bind the courts in their determination of legal rights of litigants. * * * The committee believes that, as a matter of policy in this instance, the same equitable principles and high standards that apply between individuals, should be applied by Congress as between the National Government and the sovereign states.'12 The very last paragraph of the report on the bill referred to it as 'an act of simple justice to each of the 48 States in that it reestablishes in them as a matter of law that possession and control of the lands beneath navigable waters inside their boundaries which have existed in fact since the beginning of our Nation. It is not a gift; it is a restitution.'13

Congress has thus repeatedly emphasized its desire to have the States' rights in these submerged lands determined not under 'technical rules' but, as the Senate Committee said, in accordance with 'equitable principles and high standards' of justice.14 To point out specifically what it meant, that Committee referred to three similar cases of this Court. One, which is illustrative, was State of Indiana v. State of Kentucky, 136 U.S. 479, 10 S.Ct. 1051, 34 L.Ed. 329.15 That case involved a boundary dispute between Indiana and Kentucky. The crucial question was the determination in 1890 of the location of the Kentucky boundary when Kentucky became a State in 1792. That same kind of backward-looking determination of boundaries is involved here with reference to the Gulf States. In the Indiana-Kentucky case, as here, there were no satisfactory markers, and testimony of living witnesses was deemed to be of little value. There was much evidence in the Indiana-Kentucky case, however, that Kentucky had exercised authority over the disputed territory since it first became a State and that Indiana had never challenged the boundary or the authority of Kentucky. Emphasizing the great value of that evidence this Court said: 'This long acquiescence in the exercise by Kentucky of dominion and jurisdiction over the island is more potential than the recollection of all the witnesses produced on either side. * * * It is a principle of public law universally recognized, that long acquiescence in the possession of territory, and in the exercise of dominion and sovereignty over it, is conclusive of the nation's title and rightful authority.' 136 U.S. at page 510, 10 S.Ct. at page 1054. The Court went on to quote the following from State of Rhode Island v. State of Massachusetts, 4 How. 591, 639, 11 L.Ed. 1116, 'For the security of rights, whether of state or individuals, long possession under a claim of title is protected; and there is no controversy in which this great principle may be invoked with greater justice and propriety than in a case of disputed boundary.' 136 U.S. at page 511, 10 S.Ct. at page 1054.

Accepting, as I think we should, the desire of Congress to have the ancient boundaries of these Gulf States determined on the basis of their long-unchallenged claims, rather than by the use of subtle and refined legal inferences, I am led to the conclusion that the other Gulf States, as well as Texas, are entitled to prevail over the Government here. It is admitted that prior to 1937 the United States never claimed any title to, or exercised any possession over, any part of these marginal lands, either within or without three-mile limits, except under grants from the States. On the other hand, each of the Gulf States began to exercise acts of possession, ownership, dominion and sovereignty over the marginal belt from the time of admission into the Union, without regard to any three-mile limit.16 The hearings of Congressional Committees show and their reports assert that very large sums of money have been spent by the States and their public agencies and grantees in the development and improvement of the marginal submerged lands adjacent to the States' borders.17 Not only have the States' possession, dominion and sovereignty over these marginal belts been open and notorious, but that is coupled with the fact that for much more than a century federal departments and agencies not only acquiesced in but unequivocally recognized the States' rightful claims to these belts.18 It is conceded that in many instances the Government itself has deemed it necessary to acquire title from these States before attempting to exercise any power of its own.19 There is nothing to indicate that the claims or uses of the marginal lands were ever limited to three miles. Certainly there is no evidence before us, and there was none before the Congress, that up to 1937 the United States had ever attempted to limit the sovereignty of the Gulf States within boundaries three miles from their coasts. On the other hand, evidence considered by the Congressional Committees and argued to us provides ample support for holding that the Gulf States did not consider their boundaries as limited to three miles.

The constitutions of all these States defined their boundaries when they were admitted into the Union. The first Texas Constitution kept in force the same boundary, three leagues into the Gulf, claimed for the Republic of Texas before it became a State.20 This definition was presented to Congress as a reason why Texas should be granted three leagues. The constitutions of all of the other States involved here defined their coastal boundaries as extending from one Gulf point to another 'including all islands' three or six leagues from the shore or coastline. The legislative history of the Submerged Lands Act shows that these definitions were repeatedly called to the attention of Congress as a reason why these Gulf States should be granted three leagues or more.21 From the standpoint of the paper boundary claims, Texas urges, on the basis of the more precise definition of its seaward boundary, that it has a stronger case than the other States. Although all these paper claims were considered by Congress, none was treated as decisive of the question of state boundaries, as is clearly shown by Congress' refusal to make Texas and Florida22 the exclusive beneficiaries of this Act simply because their constitutions had specifically defined a three-league seaward boundary. Nevertheless, each constitutional definition provides some color of title for each State's claim of a boundary extending at least three leagues from its coastline. The paper claims of each State, therefore, merely add some weight to the overwhelming fact, as Congress saw it, that for more than 100 years all the Gulf States exercised the only possession, dominion and sovereignty over the submerged lands adjacent to their coastlines that was ever exercised at all. The admitted facts with reference to these state boundaries thus entitle all the States to three-league marginal belts, if we fairly apply the equitable principles of prescription under which Congress declared this controversy between the Federal Government and the Gulf States should be settled.'23

The result of the Court's holding in this and the Florida case24 is that Texas and Florida will have marginal belts that uniformly extend three leagues from their shores. The other Gulf States, however, are not so fortunate. Their boundaries will extend only three miles in some places. The Government concedes, however, that their boundaries extend three miles beyond the coastline of their islands—which may be as far as six leagues from the mainland. Thus, Louisiana, Mississippi and Alabama will have irregular saw-toothed boundaries projecting six leagues at some points and retreating to within three miles of the mainland at other points. This condition follows from the Government's concession that all lands between the States' islands and the mainland are lands beneath inland waters. The mere exercise of jurisdiction over such jagged boundaries as these raises serious problems. Moreover, there is an element of fundamental unfairness about granting Texas and Florida ownership and sovereignty over three-league marginal belts while denying it to their sister States bordering the Gulf of Mexico. This is bound to frustrate the intent of Congress to settle this whole Gulf States controversy at this time.

The unfairness of the Court's result is particularly emphasized when we consider the plight in which it leaves Louisiana. One of the grounds that Congress assigned for its desire to restore these lands to the States was its strong belief that the States rather than the Federal Government should exploit their offshore oil. This desire rested on two conclusions: (1) that the States would do it better and more effectively for the interests of the public at large,25 and (2) that it would be unconscionable to take this oil away from the States after they had been solely responsible for bringing it into the public use.26 The record shows that Louisiana had leased land out more than three leagues from its coastline as early as 1920.27 There are still oil wells out there. For many years royalties from those wells have gone into the public treasury of the State of Louisiana. This income has become a part of the very life of the State.28 It constitutes a large part of the support of the State's public-school system. To take these marginal lands away from the State of Louisiana and give Texas the lands it claims—when Texas apparently has no wells at all beyond the three-mile limit—seems to me completely incompatible with the kind of justice and fairness that the Congress wanted to bring about by this Act. Moreover, I am not at all sure but that this result will completely upset the congressional desire to bring about once and for all a settlement of this long-standing controversy by passage of the Submerged Lands Act.29

Nothing in the Act itself indicates that Texas was to be given any more consideration in this case than Louisiana, Mississippi and Alabama. Had Congress wanted to give the land to Texas and refuse to give it to the other States it easily could have done so. In fact, this was specifically suggested to Congress by the Attorney General of the United States, and the Congress rejected it.30 Time and again Congress emphasized that its interests were focused on the problem of these lands because of the unfairness it saw in taking them from the Gulf States.

As Congress indicated, it is time that the problem be solved, the title be quieted and the controversy be stilled.31 In my judgment to interpret this Act in a way which grants the land to Texas and Florida and withholds it from the other Gulf States simply prolongs this costly and disquieting controversy. It will not be finally settled until it is settled the way Congress believes is right, and I do not think Congress will believe it right to award these marginal lands to Texas and Florida and deny them to the other Gulf States.

Mr. Justice DOUGLAS, dissenting in part.

Texas was admitted to the Union in 1845 (9 Stat. 108) pursuant to a prior Joint Resolution (5 Stat. 797) which reserved for adjustment by the United States 'all questions of boundary that may arise with other governments.' Texas as early as 1836 had claimed, as the opinion of the Court shows, a seaward boundary of 'three leagues from land.' Such a claim conflicted with our national policy in the Gulf, since the United States before then had in treaties with Spain (8 Stat. 252) and with Mexico (8 Stat. 372) described the boundaries between the two countries west of the Mississippi as commencing 'on the Gulf of Mexico, at the mouth of the river Sabine, in the sea.' Moreover the Convention of 1838 to establish the boundary between the United States and Texas (8 Stat. 511) agreed to the running and marking of 'that portion of the said boundary which extends from the mouth of the Sabine, where that river enters the Gulph of Mexico, to the Red river.' Certainly in that Convention Texas was not going so far as to claim, as she had earlier, 'three leagues' into the Gulf.

I agree with the Court that there was nothing done at or subsequent to that time to approve the Texas claim to three leagues from land unless it be the Treaty of Guadalupe Hidalgo signed on February 2, 1848, 9 Stat. 922, by the United States and Mexico and which, inter alia, fixed the 'boundary line between the two republics' in the Gulf of Mexico 'three leagues from land, opposite the mouth of the Rio Grande.' Can we say that the United States sat at that conference table negotiating for Texas and her boundary claim? Was the seaward boundary once claimed by Texas now claimed by the United States in recognition that Texas owned it?

There is not a word in the history of the negotiations to indicate that the United States had moral or legal claim to the three-league belt because of the earlier claim of Texas. There is no suggestion that the United States claimed derivatively from the right of Texas and thus upheld the position of Texas, approving the claim made by Texas in 1836. There is not a word indicating that the Treaty of 1848 was in form or in essence an undertaking by Congress to fix the boundaries of Texas under the 1838 convention.

The terms of the 1838 Convention do not support any such construction for, as I have said, that Convention fixed the boundary as extending 'from the mouth of the Sabine, where that river enters the Gulph of Mexico,' not 'three leagues' seaward of that point. To conclude, therefore, that the Treaty of Guadalupe Hidalgo was intended to fix the land and sea boundaries of Texas in accordance with the Texas Boundary Act of 1836 is to indulge in mental gymnastics beyond my capacities. The agreement by the United States to fix the boundaries of Texas was not contained in the unilateral act of Texas reflected in her 1836 statute but by the Convention of 1838 which required the seaward boundary to extend from 'the mouth of the Sabine, where that river enters the Gulph of Mexico.' The obligation in this Convention thus is at war with any inference that the seaward boundary was to be 'three leagues' from shore. Cf. United States v. State of Texas, 162 U.S. 1, 32, 16 S.Ct. 725, 731, 40 L.Ed. 867.

While the 1838 Convention failed to include any seaward territory, a Joint Commission appointed to make the survey pursuant to the 1838 Convention actually marked the boundary between the United States and the Republic of Texas at the mouth of the Sabine River—not three leagues into the Gulf of Mexico.1

It is true that the Joint Resolution of 1845 (5 Stat. 797) called for the formation of Texas 'subject to the adjustment by this government of all questions of boundary that may arise with other governments.' But the situation envisaged by that clause soon changed. The Mexican war broke out in 1846; and the Treaty of Guadalupe Hidalgo finally brought it to a close. By the time the treaty negotiations started the United States was thinking in new dimensions. The problem was no longer finding and establishing what the Texas boundaries had been. We then put that question to one side. The instructions to our representative, Nicholas P. Trist, which included a projet of the Treaty, read in part, 'The extension of our boundaries over New Mexico and Upper California, for a sum not exceeding twenty millions of dollars, is to be considered a sine qua non of any treaty. You may modify, change, or omit the other terms of the proje t if needful, but not so as to interfere with this ultimatum.'2 If Lower California was included, Trist was authorized to pay up to $25,000,000.3 Trist recorded at his first conference with the Mexican Commissioners that 'our claim for extension of territory' was placed 'on the ground of indemnity for the expenses of the war.'4 The acquisition of territory from Mexico as indemnity was repeated over and again by President Polk in his message of December 7, 1847.5 Thus he said, '* * * if no Mexican territory was acquired, no indemnity could be obtained.'6 Again, '(t)he doctrine of no territory is the doctrine of no indemnity.'7 And what he went on to say should remove any doubts about the nature of the controversy with Mexico. First, it will be apparent from what follows that 'three leagues' were not a part of his thinking when it came to the seaward boundary. Second, it is obvious that the sole preoccupation was with the acquisition of land from Mexico.8

'The commissioner of the United States was authorized to agree to the establishment of the Rio Grande as the boundary, from its entrance into the Gulf to its intersection with the southern boundary of New Mexico, in north latitude about thirty-two degrees, and to obtain a cession to the United States of the provinces of New Mexico and the Californias, and the privilege of the right of way across the isthmus of Tehuantepec. The boundary of the Rio Grande, and the cession to the United States of New Mexico and Upper California, constituted an ultimatum which our commissioner was, under no circumstances, to yield.

'That it might be manifest not only to Mexico, but to all other nations, that the United States were not disposed to take advantage of a feeble power, by insisting upon wresting from her all the other provinces, including many of her principal towns and cities, which we had conquered and held in our military occupation, but were willing to conclude a treaty in a spirit of liberality, our commissioner was authorized to stipulate for the restoration to Mexico of all our other conquests.

'As the territory to be acquired by the boundary proposed might be estimated to be of greater value than a fair equivalent for our just demands, our commissioner was authorized to stipulate for the payment of such additional pecuniary consideration as was deemed reasonable.' (Italics added.)

And when the Treaty had been ratified by both countries and President Polk reported to Congress, he did not speak of settlement of any boundaries of the former State of Texas. He stated, 'The extensive and valuable territories ceded by Mexico to the United States constitute indemnity for the past.'9 And he expounded on the valued additions of New Mexico and Upper California to our domain.10 There is no mention of any settlement of any claim of Texas to a seaward boundary 'three leagues' off shore. Nor is there any reference to any boundary settlement based on old Texas claims. This is not surprising, for the Treaty of Guadalupe Hidalgo was part of our empire building, not the determination of old boundaries.

The Treaty of Guadalupe Hidalgo has until now never been considered to have played any part in determining any Texan boundary question. As stated by the Court in United States v. State of Texas, 162 U.S. 1, 16 S.Ct. 725, 40 L.Ed. 867, the boundary question was resolved by the Act of September 9, 1850 (9 Stat. 446). After quoting the 1836 Act by which Texas claimed 'three leagues from land' as her seaward border, the Court went on to say:

'This boundary had not been defined when Texas was admitted, as a State, into the Union, with the territory 'properly included within and rightfully belonging to the Republic of Texas.' The settlement of that question, together with certain claims made by Texas against the United States, were among the subjects that engaged the attention of congress during the consideration of the various measures constituting the compromises of 1850. The result was the passage of the above act of September 9, 1850, c. 49, the provisions of which were promptly accepted by the State of Texas. This legislation of the two governments constituted a convention or contract in respect of all matters embraced by it. The settlement of 1850 fixed the boundary of Texas 'on the north' to commence at the point at which the 100th meridian intersects the parallel of 36 30 north latitude, and from that point the northern line ran due west to the 103d meridian, thence due south to the 32d degree of north latitude, thence on that parallel to the Rio Bravo del Norte, and thence with the channel of that river to the Gulf of Mexico.' 162 U.S. at page 39, 16 S.Ct. at page 733.

Drawing the line 'to the Gulf of Mexico' is a far cry from drawing it to a point 'three leagues' from the shore. What we do today is quite inconsistent with what a unanimous Court in United States v. State of Texas, supra, decided in 1896. What the Court said was not decided until 1850 we now say was decided earlier.

Though the United States and Mexico by the Treaty of Guadalupe Hidalgo established land boundaries between the two countries, Congress never recognized that the Treaty established any boundaries of Texas. In her 1836 statute, Texas not only claimed the three-league belt in the Gulf of Mexico but also much of the territory lying west and north of her present boundaries, including eastern New Mexico which, like the three-league belt, was acquired under the Treaty by the United States. Congress in the 1850 compromise paid Texas $10,000,000 to relinquish its claim to this territory. Yet this payment was regarded by Congress not as purchase price but as settlement of a disputed claim.11 Accordingly, it was early held that eastern New Mexico, though claimed by Texas, was not brought into the Union by the Joint Resolution of 1845 and that the Treaty of Guadalupe Hidalgo did not establish what the Texas boundaries had been at the time of its annexation. De Baca v. United States, 1901, 36 Ct.Cl. 407. I cannot understand how the Treaty can be said to have established a seaward boundary when it did not fix the inland boundaries of Texas. The Court does not suggest that all the land claimed by Texas in her 1836 statute and subsequently ceded to the United States in the Treaty of Guadalupe Hidalgo was 'territory properly included within, and rightfully belonging to the Republic of Texas' within the meaning of the Joint Resolution of 1845. Yet I can see no basis for deciding that the Treaty, though not recognizing the validity of the western boundary claims of Texas, did establish and fix other Texas boundaries.12 If the Government was not negotiating on behalf of Texas in acquiring the eastern New Mexico territory, how can it be said to have done so with respect to the seaward boundary claim?

The southwestern boundary of Texas was confirmed in the 1850 Compromise to lie along the Rio Grande 'to the Gulf of Mexico.' The 1838 Convention had fixed the eastern boundary at 'the mouth of the Sabine.' Thus, on the two occasions when the United States and Texas negotiated and agreed upon boundaries and when they would have been most likely to have settled the question, no extension of the Texas territory into the Gulf was recognized. The conclusion for me is irresistable that the seaward boundary, so far as Texas was concerned, was so inconsequential as to require or receive no settlement. I conclude that in terms of § 4 of the 1953 Act the boundary of Texas reserved for later adjudication when Texas was admitted to the Union was on its seaward side never approved by Congress to be three leagues from shore.

Why then the reference in the Treaty to the 'Boundary line' between the United States and Mexico as 'three leagues' from land in the Gulf of Mexico?

The Court says that the United States in negotiating the Treaty attempted to follow the 1836 Texas Act. The project of the Treaty given to Trist did provide for a boundary line commencing 'three leagues from the land opposite the mouth of the Rio Grande.'13 But neither it nor the accompanying instructions made any reference to the 1836 Act of Texas. Trist was not told to take the 1836 Act as his guide when it came to seaward boundaries. I can find nothing in the instructions to Trist which relates his duties in negotiating the Treaty to what Texas had claimed in 1836, nor does the Court refer us to any such instruction. To be sure, Trist's predecessor, John Slidell, had been advised by the Secretary of State, Mr. Buchanan, in a letter dated November 10, 1845, that 'The Congress of Texas, by the act of December 19, 1836, have declared the Rio del Norte (Rio Grande), from its mouth to its source, to be a boundary of that republic.'14 Trist knew of these earlier instructions.15 Yet if he followed them literally he would have negotiated a boundary beginning 'at the mouth' of the Rio Grande not 'three leagues from land opposite the mouth.'16 And, as I have pointed out, the purpose of Trist's mission was much different from that of Slidell's. Slidell was sent to Mexico before the war to settle a boundary dispute. Trist went to obtain the fruits of our conquest of Mexico. The Court concedes that Slidell's instructions demonstrate 'total insensitivity to any problem of a seaward boundary.' I agree. But I cannot take the additional step that, although our State Department was wholly insensitive to the problem of a seaward boundary, it was nonetheless trying to stand in the shoes of Texas and get Mexico to validate the old boundary claims of Texas. So far as I can deduce, this is sheer speculation.

Much less speculative is the reason advanced in 1875 by Hamilton Fish, Secretary of State.

In 1874 Lord Derby had raised for Great Britain a question with regard to Spain's claim of jurisdiction of two leagues from the Spanish coast.17 Hamilton Fish replied on January 22, 1875, as follows:18

'* * * I have the honor to inform you that this Government has uniformly, under every administration which has had occasion to consider the subject, objected to the pretension of Spain adverted to, upon the same ground and in similar terms to those contained in the instruction of the Earl of Derby.

'We have always understood and asserted that, pursuant to public law, no nation can rightfully claim jurisdiction at sea beyond a marine league from its coast.

'This opinion on our part has sometimes been said to be inconsistent with the facts that, by the laws of the United States, revenuecutters are authorized to board vessels anywhere within four leagues of their coasts, and that by the treaty of Guadalupe Hidalgo, so called, between the United States and Mexico, of the second of February, 1848, the boundary line between the dominions of the parties begins in the Gulf of Mexico, three leagues from land.

'It is believed, however, that in carrying into effect the authority conferred by the act of Congress referred to, no vessel is boarded, if boarded at all, except such a one as, upon being hailed, may have answered that she was bound to a port of the United States. At all events, although the act of Congress was passed in the infancy of this Government, there is no known instance of any complaint on the part of a foreign government of the trespass by a commander of a revenue-cutter upon the rights of its flag under the law of nations.

'In respect to the provision in the treaty with Mexico, it may be remarked that it was probably suggested by the passage in the act of Congress referred to, and designed for the same purpose, that of preventing smuggling. By turning to the files of your legation, you will find that Mr. Bankhead, in a note to Mr. Buchanan of the 30th of April, 1948, objected on behalf of Her Majesty's government, to the provision in question. Mr. Buchanan, however, replied in a note of the 19th of August, in that year, that the stipulation could only affect the rights of Mexico and the United States, and was never intended to trench upon the rights of Great Britain, or of any other power under the law of nations.'

The Act referred to was that of March 2, 1799 (1 Stat. 627), which provided in § 54 that it shall be lawful for our collectors, naval officers, inspectors, and officers of revenue cutters to board ships bound to the United States 'within four leagues of the coast' for the purpose of controlling or preventing smuggling.19

That this was the purpose gains collateral support from a series of treaties concluded by Mexico in the latter half of the nineteenth century with China,20 the Dominican Republic,21 El Salvador,22 France,23 Germany,24 the Netherlands,25 Norway and Sweden,26 and the United Kingdom,27 which state that the 'three league' belt (or at times a broader one) was being used for certain limited reasons of law enforcement.

These treaties reflect what Hamilton Fish as Secretary of State said about the Treaty of Guadalupe Hidalgo and its 'three league' provision. They show a practice of exercising extraterritorial regulation beyond the usual three-mile limit with respect to customs and smuggling. It is true that the Treaty of Guadalupe Hidalgo speaks in terms of 'boundary.' But, if it meant 'boundary' in the technical property sense, it would mark a line that separated the territory of the United States and Mexico and established a territorial claim good against all comers. Our State Department from the beginning insisted that was not intended. When Great Britain protested in 1848 that the Treaty of Guadalupe Hidalgo did not respect the three-mile limit which 'is acknowledged by international law and practice as the extent of territorial jurisdiction over the sea that washes the coasts of states,' Secretary of State Buchanan's answer (which, as we have noted, Hamilton Fish referred to in his communication of January 22, 1875) was as follows:28

'In answer I have to state, that the stipulation in the treaty can only affect the rights of Mexico and the United States. If for their mutual convenience it has been deemed proper to enter into such an arrangement, third parties can have no just cause of complaint. The Government of the United States never intended by this stipulation to question the rights which Great Britain or any other power may possess under the law of nations.'

That has consistently been our construction. I have already referred to what Secretary Fish said in 1875. When Mexico in 1935 undertook to extend the breadth of Mexican territorial waters from three to nine miles,29 our Ambassador Josephus Daniels on instructions from the State Department protested, reserving 'all rights of whatever nature so far as concerns any effects upon American commerce from enforcement of this legislation.'30 And when Mexico in reply31 referred to the Treaty of Guadalupe Hidalgo as justifying her claim to nine miles, the State Department reiterated among other things our consistent position that the treaty provision extending the 'boundary' into the Gulf for three leagues was included to give the two nations jurisdiction to that distance at that particular point 'to prevent smuggling.'32

It seems apparent from this history that the United States in negotiating the Treaty of Guadalupe Hidalgo was far from determining that the metes and bounds of our property on the seaward side of the Gulf ran to three leagues. The three-league provision in purpose and presumed effect had quite a different aim. It had no aim to assert derivatively a title that Texas had claimed. Its aim was merely to mark a zone where, so far as the two contracting parties were concerned, our law enforcement agencies could maintain effective patrols. If this history shows nothing else, it shows that the United States had a national interest in having the three-league belt recognized for its own purposes, whereas Texas up to the time oil was discovered offshore placed no value whatsoever on a seaward boundary. For me the argument becomes too thin to say that the United States, though nominally negotiating on her own behalf, was claiming the three-league maritime belt on behalf of Texas.

If we acted today with the precision and meticulous care which is demanded in title disputes, we could not, I think, say that the United States in the Treaty of Guadalupe Hidalgo recognized or approved the Texas claim that the territory of Texas extended three leagues from shore.

Yet if we are to decide these cases by substandards (lessening the requirements of proof as we should do if Congress intended to grant whatever the parties fairly claimed), then I agree with Mr. Justice Black that the discrimination in favor of Texas and against Louisiana, Alabama, and Mississippi is quite unjustified.

If the southeast corner of Texas was three leagues offshore, it is difficult for me to see how the southwest corner of Louisiana was not at the same point. From the beginning the United States and Spain fixed their corner west of the Mississippi 'on the Gulph of Mexico, at the mouth of the river Sabine, in the sea.' 8 Stat. 254. If we move the Texas boundary out three leagues, it is hard to see why Louisiana's does not accompany it. It has long been recognized that a part of Louisiana's border is 'a water boundary' that extends 'to the open sea or Gulf of Mexico,' State of Louisiana v. State of Mississippi, 202 U.S. 1, 43, 26 S.Ct. 408, 419, 50 L.Ed. 913, and includes 'the deep-water sailing channel line as a boundary.' Id., 202 U.S. at page 44, 26 S.Ct. at page 419.

The enabling Act authorizing the people of the Territory of Orleans to form Louisiana described the territory as running 'to the gulf of Mexico; thence bounded by the said gulf * * * including all islands within three leagues of the coast.' 2 Stat. 641. The boundaries described in the Act admitting Louisiana to the Union are similarly described as 'to the gulf of Mexico; thence, bounded by the said gulf * * * including all islands within three leagues of the coast.' 2 Stat. 701, 702.

As respects Mississippi, Congress in the Enabling Act (3 Stat. 348) provided that the territory included in the new State would run from a specified point on the Gulf of Mexico 'westwardly, including all the islands within six leagues of the shore.' This was the boundary description used since George III of Great Britain described West Florida as 'bounded to the southward by the Gulf of Mexico, including all islands within six leagues of the coast.'33

Alabama when a territory had two of its boundaries described as 'thence due south to the Gulf of Mexico, thence east-wardly, including all the islands within six leagues of the shore, to the Perdido river.' 3 Stat. 371. This language was repeated in the Enabling Act. 3 Stat. 489.

The United States concedes that, so far as Louisiana, Mississippi and Alabama are concerned, all the submerged lands between the mainland and the islands are sufficiently enclosed to constitute inland waters that passed to the State on its entry into the Union. Pollard v. Hagan, 3 How. 212, 11 L.Ed. 565. It further concedes that these States have rights to the submerged lands within three miles of the islands under the ordinary three-mile rule.

If we were to require the degree of proof of ownership which is ordinarily required in title disputes, I would agree that neither Louisiana, Alabama, nor Mississippi has met the burden of proof. But if standards and requirements as lax as those used to grant Texas three leagues from shore are sufficient for her, they should be sufficient for these other three States.

The heart of the Texan claim is that the United States and Mexico recognized that there was a three-league maritime belt which each would respect and that this was done in recognition of the validity of the claims contained in the 1836 statute of Texas. This belt was called a 'boundary'; but, as I have tried to demonstrate, it was not a territorial claim but only a demarcation of zones where the parties' respective law enforcement activities would be recognized and approved. The Gulf presents peculiar problems due to its shallow coast. The shallowness of its waters is well documented and our Government was well aware of this condition in 1848.34 These are the persuasive facts behind the creation of the three-league belt by the Treaty of Guadalupe Hidalgo and by Mexico in the other treaties concerning the Gulf which she negotiated with other nations.

If the policy of measuring the zone of the United States as 'three leagues' into the Gulf off the shore of Texas is to give Texas property rights to the submerged lands in that zone, the beneficiaries of that concern should be all our Gulf States. At best the language used to describe the seaward territories of Louisiana, Alabama, and Mississippi is ambiguous. The words 'to the Gulf of Mexico * * * including all of the islands' within certain designated leagues of the shore can reasonably mean that the 'boundary line' is marked by the islands. There is difficulty in that construction. Yet it is for me no more difficult than the method we use to give Texas a territorial claim in the same belt. All the States on the Gulf should be given the same benefit of the doubts that have been resolved in favor of Texas. The claim of Florida, as shown in United States v. State of Florida, 363 U.S. 121, 80 S.Ct. 1026, is fully established by the standard I would ask Texas to meet. If we are to relax the standard of proof for the benefit of Texas, we should do so for all these claimants. In that posture, the claims of each of the other Gulf States which have gone 'long-unchallenged,' as shown by Mr. Justice Black, are as clear as those of Texas.

Mr. Justice BLACK delivered the opinion of the Court.

This controversy involves the interests of all five Gulf States—Florida, Texas, Louisiana, Mississippi and Alabama—in the submerged lands off their shores. The Court heard the claims together, but treats them in two opinions. This opinion deals solely with Florida's claims. The result as to the other States is discussed in one opinion, at 363 U.S. 1, 80 S.Ct. 961. All the claims arise and are decided under the Submerged Lands Act of 1953.1

The Act granted to all coastal States the lands and resources under navigable waters extending three geographical miles seaward from their coastlines. In addition to the three miles, the five Gulf States were granted the submerged lands as far out as each State's boundary line either 'as it existed at the time such State became a member of the Union,' or as previously 'approved by Congress,' even though that boundary extended further than three geographical miles seaward. But in no event was any State to have 'more than three marine leagues into the Gulf of Mexico.'2 This suit was first brought against Louisiana by the United States, United States v. State of Louisiana, 350 U.S. 990, 76 S.Ct. 541, 100 L.Ed. 856, invoking our original jurisdiction under ART. III, § 2, cl. 2, of the Constitution, to determine whether Louisiana's boundary when it became a member of the Union extended three leagues or more into the Gulf, as Louisiana claimed, so as to entitle it to the maximum three-league grant of the Submerged Lands Act. After argument on the Government's motion for judgment against Louisiana, we suggested that the interests of all the Gulf States under the Act were so related, 'that the just, orderly, and effective determination' of the issues required that all those States be before the Court. United States v. State of Louisiana, 354 U.S. 515, 516, 77 S.Ct. 1373, 1 L.Ed.2d 1525. All are now defendants, each has claimed a three-league boundary and grant, which the United States denies, and the issues have been extensively briefed and argued by the parties. As stated, this opinion deals only with the United States-Florida controversy.

Florida contends that the record shows it to be entitled under the Act to a declaration of ownership of three marine leagues of submerged lands, because (1) its boundary extended three leagues or more seaward into the Gulf when it became a State, and (2) Congress approved such a three-league boundary for Florida after its admission into the Union and before passage of the Submerged Lands Act. Since we agree with Florida's latter contention, as to congressional approval, we find it unnecessary to decide the boundaries of Florida at the time it became a State.

Florida claims that Congress approved its three-league boundary in 1868, by approving3 a constitution submitted to Congress as required by a Reconstruction Act passed March 2, 1867. 14 Stat. 428. That constitution carefully described Florida's boundary on the Gulf of Mexico side as running from a point in the Gulf 'three leagues from the mainland' and 'thence northwestwardly three leagues from the land' to the next point.4 The United States concedes that from 1868 to the present day Florida has claimed by its constitutions a three-league boundary into the Gulf.5 The United States also admits that Florida submitted this constitution to Congress in 1868, but denies that the Gulf boundary it defined was 'approved' by Congress within the meaning of the Submerged Lands Act.6 This is the decisive question as between Florida and the United States.

The 1868 Florida Constitution was written and adopted by Florida pursuant to the congressional Act of March 2, 18677 as supplemented by a second Act of March 23, 1867.8 These Reconstruction Acts purported 'to provide for the more efficient government of the Rebel States,' including Florida. The States involved were divided into military districts and subject to strict military authority. Detailed provisions were made for registration of voters, election of delegates to constitutional conventions, the framing of constitutions 'in conformity with the provisions' of these Reconstruction Acts, and submission of the constitutions to the people of those States for their ratification and approval—all under the supervision and control of commanding generals. Constitutions so adopted were then to be 'submitted to Congress for examination and approval,' after which approval by Congress and after ratification of the Fourteenth Amendment by each State, each should be 'declared entitled to representation in Congress.' Florida's Constitution was written, considered and voted upon in the State in accordance with these statutory directions and under the eye and control of an Army general. When submitted to Congress it was much debated, and thereafter on June 25, 1868, another Act was passed authorizing the admission of Florida and other Southern States 'to Representation in Congress.'9 15 Stat. 73. The preamble to this 'Admission Act' declared that these States had adopted their constitutions 'in pursuance of the provisions' of the 1867 Acts, which Acts, as has been pointed out, required 'examination and approval' of the constitutions as a prerequisite to readmission of congressional representation. Thus by its own description, Congress not only approved Florida's Constitution which included three-league boundaries, but Congress in 1868 approved it within the meaning of the 1867 Acts. In turn, the approval the 1867 Acts required appears to be precisely the approval the 1953 Act contemplates.

The Government argues, however, that these readmission enactments did not contemplate and Congress did not make a general scrutiny of all the provisions of the state constitutions, but only that the constitutions had been duly adopted and were republican in form. The Government makes many references to debates which indicated that some Senators and Congressmen were satisfied with such a limited examination of the constitutions.10 Florida, on the other hand, points out many other remarks which indicated a much closer examination of the state constitutions.11

It is beyond doubt that the proposed constitutions were printed, then read, discussed, and amended in the Congress. For instance, the very 1868 bill that admitted Florida's congressional representatives contained a proviso rejecting certain parts of the Georgia Constitution.12 That at least some Congressmen scrutinized the constitutions to see if amendments were necessary is persuasively shown by the remarks of Congressman Thaddeus Stevens, set out below.13 Mr. Stevens was Chairman of the all-important Joint Committee on Reconstruction, and, because of his leading role as architect of the reconstruction plan finally adopted and carried out by Congress, has appropriately been called 'the Father of the Reconstruction.'14

The voluminous references to the Reconstruction debates fail to show us precisely how closely the Southern States' Reconstruction Constitutions were examined. We cannot know, for sure, whether all or any of the Congressmen or Senators gave special attention to Florida's boundary description. We are sure, however, that this constitution was examined and approved as a whole, regardless of how thorough that examination may have been, and we think that the 1953 Submerged Lands Act requires no more than this. Moreover, the Hearings and the Reports on the Submerged Lands Act show, as the Government's brief concedes, that those who wrote into that measure a provision whereby a State was granted up to three leagues if such a boundary had been 'heretofore approved by Congress,' had their minds specifically focused on Florida's claim based on submission of its 1868 Constitution to Congress. When Florida's claims were mentioned in the hearings it was generally assumed that Congress had previously 'approved' its threeleague boundaries.15 The Senate Report on a prior bill, set forth as a part of the report on the 1953 Act, pointed out that 'In 1868 Congress approved the Constitution of Florida, in which its boundaries were defined as extending 3 marine leagues seaward and a like distance into the Gulf of Mexico.' S.Rep.No. 133, 83d Cong., 1 Sess. 64-65.16 The language of the Submerged Lands Act was at least in part designed to give Florida an opportunity to prove its right to adjacent submerged lands so as to remedy what the Congress evidently felt had been an injustice to Florida. Upon proof that Florida's claims met the statutory standard—'boundaries * * * heretofore approved by the Congress'—the Act was intended to 'confirm' and 'restore' the three-league ownership Florida had claimed as its own so long and which claim this Court had in effect rejected in United States v. State of Texas, 339 U.S. 707, 70 S.Ct. 918, 94 L.Ed. 1221; United States v. State of Louisiana, 339 U.S. 699, 70 S.Ct. 914, 94 L.Ed. 1216; and United States v. State of California, 332 U.S. 19, 67 S.Ct. 1658, 91 L.Ed. 1889. As previously shown, Congress in 1868 did approve Florida's claim to a boundary three leagues from its shores. And, as we have held, the 1953 Act was within the power of Congress to enact. State of Alabama v. State of Texas, 347 U.S. 272, 74 S.Ct. 481, 98 L.Ed. 689. See also United States v. State of California, 332 U.S. 19, 27, 67 S.Ct. 1658, 1663, 91 L.Ed. 1889.

We therefore deny the United States' motion for judgment. We hold that the Submerged Lands Act grants Florida a three-marine-league belt of land under the Gulf, seaward from its coastline, as described in Florida's 1868 Constitution. The cause is retained for such further proceedings as may be necessary more specifically to determine the coastline, fix the boundary and dispose of all other relevant matters. The parties may submit an appropriate form of decree giving effect to the conclusions reached in this opinion. It is so ordered.

The United States' motion for judgment denied.

The CHIEF JUSTICE and Mr. Justice CLARK took no part in the consideration or decision of this case.

Mr. Justice FRANKFURTER, whom Mr. Justice BRENNAN, Mr. Justice WHITTAKER and Mr. Justice STEWART join, concurring.*

Considering the variety of views evoked by these cases, I deem it appropriate to add a few words to the two Court opinions which I have joined.

The one thing which I take to be incontestable is that Congress did not, by the Submerged Lands Act of 1953, make an outright grant to any of the Gulf States in excess of three miles. Congress only granted to each of these States the opportunity to establish at law that it possessed a boundary in excess of three miles, either by virtue of possession of such a boundary at the time of its admission to the Union or by virtue of congressional 'approval' of such a boundary prior to the enactment of the Submerged Lands Act. A Gulf State that can successfully establish such a judicially ascertainable fact is entitled to a grant of the submerged lands beyond three miles to a distance of the lesser of three leagues or of the boundary so established. Congress, in the Submerged Lands Act itself, did not determine the existence of a boundary for any State beyond three miles, either explicitly or by implied approval of a claim presented to it in the course of the legislative process. Nor of course did Congress vest this Court with determination of a claim based on 'equity' in the layman's loose sense of the term, for it could not. Congress may indulge in largess based on considerations of policy; Congress cannot ask this Court to exercise benevolence on its behalf.

There is no foundation in the Act of 1953 or its legislative history for the view that particularized, express approval of a State's boundary claim by a prior Congress is required to make a defined boundary the measure of the grant. To the contrary, in the case of Florida, authoritative legislative history makes it perfectly clear that the very question deliberately preserved by the Act of 1953 was whether congressional approval of the new Florida Constitution in the Reconstruction legislation of 1867 1868, by which Florida was restored to full participation in the Union, amounted to an approval of the three-league boundary which that constitution explicitly set forth.* I sustain Florida's claim because I find that its boundary was so approved.

The proper construction of the effect of congressional 'approval' of the Florida Reconstruction constitution presents problems quite different from those stirred by the constitutional controversy and its resulting problems that are compendiously known as Reconstruction. See Lincoln's last public address, April 11, 1865. 8 Basler, The Collected Works of Abraham Lincoln, 399. The readjustment of the relationship between the States that had remained in the Union and those that had seceded presented major issues not only for the political branches of the Government, the President and the Congress, but also for this Court. Insofar as the perplexing and recalcitrant problems of Reconstruction involved legal solutions, the evolution of constitutional doctrine was an indispensable element in the process of healing the wounds of the sanguinary conflict. It was in aid of that process that this Court formulated the doctrine expressed in the famous sentence in State of Texas v. White: 'The Constitution, in all its provisions, looks to an indestructible Union, composed of indestructible States.' 7 Wall. 700, 725, 19 L.Ed. 277.

This theory served as a fruitful means for dealing with the problems for which it was devised. It is unrelated to the question now before us, namely, whether, when it 'approved' as an entirety the Florida Constitution as a condition to the recognition of that State's full membership in the Union, Congress exercised its undoubted power to approve the seaward boundary claim contained within it. It is in essence the contention of the United States that approval could only have been manifested explicitly, that Congress must have ratified the boundary provision in so many words, either expressly in the Reconstruction Acts, or by an authoritative gloss upon them in a committee report or a speech on the floor by a responsible chairman. But in these matters we are dealing with great acts of State, not with fine writing in an insurance policy. Florida was directed to submit a new constitution for congressional approval as a prerequisite for the exercise of her full rights in the Union of States and the resumption of her responsibilities. In this context it would attribute deceptive subtlety to the Congresses of 1867—1868 to hold that it is necessary to find a formal, explicit statement by them, whether in statutory text or history, that the boundary claim, as submitted in Florida's new constitution, was duly considered and sanctioned, in order to find 'approval' of that claim.

Mr. Justice HARLAN, dissenting.

It is with regret that I find myself unable to agree that Florida has made a case for 'three-league' rights under the Submerged Lands Act. As shown in the Court's opinion relating to the other States involved in the litigation (363 U.S. at pages 16 36, 80 S.Ct. at pages 971—982), a state seaward boundary satisfying the requirements of the Submerged Lands Act must be one which by virtue of Congressional action would have been legally effective to carry, as between State and Nation, submerged land rights under the Pollard rule, as Congress conceived that rule to have been prior to this Court's decision in the California case, 332 U.S. 19, 67 S.Ct. 1658, 91 L.Ed. 1889. That test supplies the meaning and content not only of the phrase 'boundaries * * * as they existed at the time such State became a member of the Union,' but also of the phrase 'boundaries * * * as heretofore approved by the Congress,' contained in § 2 of the Submerged Lands Act (363 U.S. at page 10, 80 S.Ct. at page 968, note 7). Florida must satisfy that test if it is to prevail in this case.

The Court's Florida opinion conceives the issue to be whether Congress in 1868 made a 'general scrutiny of all the provisions of' Florida's Constitution, and states that the Submerged Lands Act requires only that it have been 'examined and approved as a whole.' The concurring opinion asserts that the relevant inquiry is 'whether congressional approval of the new Florida Constitution * * * amounted to an approval of the three-league boundary which that constitution explicitly set forth.' In my view, neither formulation adequately characterizes the nature of the question left by the Submerged Lands Act to this Court. It may be conceded that Congress scrutinized all the provisions of Florida's Constitution and that by accepting the Constitution it, in an abstract sense, approved the boundary provision. The further and controlling inquiry that must be made is whether the legal effect of such action was to establish a valid three-league boundary for Florida. If not, Florida would not have owned the submerged lands to that distance under Congress' concept of the Pollard rule, and it would therefore be entitled to no better rights under the Submerged Lands Act. On neither branch of its claims do I believe that Florida's showing measures up to that standard.

My difficulty with Florida's 'readmission' claim begins with the proposition that a State relying on a readmission boundary stands on quite a different legal footing than one relying on an original admission boundary. In the latter instance the fixing of a boundary is a necessary incident of Congress' power to admit new States. A newly admitted State, in the absence of an express fixation of its boundary by the Congressional act of admission or an articulated rejection of its preadmission boundary, may, I think, rely on a presumed Congressional purpose to adopt whatever boundary the political entity had immediately prior to its admission as a State.1 That would seem to be the effect of State of New Mexico v. State of Colorado, 267 U.S. 30, 45 S.Ct. 202, 69 L.Ed. 499, and State of New Mexico v. State of Texas, 275 U.S. 279, 48 S.Ct. 126, 72 L.Ed. 280; 276 U.S. 557, 48 S.Ct. 437, 72 L.Ed. 698.2

Different considerations, however, obtain in the case of a State readmitted to 'representation in Congress' after the Civil War. Such a State renounced the Union with boundaries already fixed by Congress at the time of original admission. When it was restored to full participation in the Union, there is no reason to suppose its territorial limits would not remain the same. So much indeed finds sound support in the constitutional doctrines evolved in the so-called reconstruction cases, even though they related to different problems arising out of the Civil War. See State of Texas v. White, 7 Wall. 700, 726, 19 L.Ed. 227; White v. Hart, 13 Wall. 646, 649—652, 20 L.Ed. 685; Gunn v. Barry, 15 Wall. 610, 623, 21 L.Ed. 212; Keith v. Clark, 97 U.S. 454, 461, 24 L.Ed. 1071. Since, as will be shown later (80 S.Ct. at page 1036), Florida renounced the Union with a seaward boundary no greater than three miles, the issue here is whether upon readmission Congress changed that boundary to three leagues. Unlike the situation at original admission, where the necessity of fixing some boundary for a newly admitted State leads readily to the presumption of Congressional approval of a tendered preadmission boundary, no similar presumption arises in connection with an alleged change in a state boundary already fixed by Congress.

After a painstaking examination of the legislative materials I can find no evidence whatever that the Congress intended to change Florida's seaward boundary from one not in excess of three miles to one of three leagues when the State was readmitted to representation in 1868. Certainly the Act of readmission (Act of June 25, 1868, 15 Stat. 73), upon which Florida relies, affords no basis for a claim that Congress expressly approved the State's three-league boundary provision.3 The statute refers in no way to boundaries; it does not even undertake to approve Florida's Constitution, let alone the boundaries described therein; and it is entitled merely as 'An Act to admit * * * Florida, to Representation in Congress,' not as an act to admit it to the Union. Cf. White v. Hart, supra, 13 Wall. at page 652.4

Nor can I find any basis in the legislative record for a conclusion that Congress impliedly changed Florida's boundary. The Congressional debates and reports may be searched in vain for a single reference—even a causal one—to the boundaries of any of the readmitted States. The preamble of the Act of June 25, 1868, and the Congressional debates affirmatively show that all with which Congress was concerned was whether the constitutions of the readmitted States had been validly adopted and were republican in structure, and, in a few instances, whether they contained provisions in palpable violation of the Federal Constitution.5 No territorial questions at all appear to have figured in the debates. In these circumstances the case of State of Virginia v. State of Tennessee, 148 U.S. 503, 13 S.Ct. 728, 37 L.Ed. 537, upon which Florida relies in support of its argument as to implied approval, is quite inapposite. There the two States had made a compact with respect to the boundary between them. Subsequently Congress adopted the line so established in setting up districts for judicial, revenue, election, and appointive purposes. It was held that Congress had thereby impliedly approved the interstate compact. Id., 148 U.S. 521—522, 13 S.Ct. 735—736. In the present instance we have no affirmative action by Congress respecting the 1868 proffered Florida boundary in any way comparable to that in this earlier case.

Nor can a purpose to change Florida's boundary be inferred from the bare context of the Congressional action. The constitutional area in which the Congress was moving in 1868 should not be forgotten. Congress was not undertaking to exercise its power to fix state boundaries incident to the admission of new States. Rather, it was engaged in 're-establishing the broken relations of the State(s) with the Union,' and in satisfying itself that the constitutions of the States lately in rebellion had been validly adopted and were republican in form, all pursuant to Congress' constitutional obligation to guarantee to each State a republican form of government. See State of Texas v. White, supra, 7 Wall. 727—728. This is not to say that Congress could not at the same time have changed any State's original admission boundary, but only to raise the question whether it in fact did so. While the exercise of a particular constitutional power does not of course preclude resort to others, the nature of the power exerted in 1868 does seem to me to negative the idea that Congress also purported to exercise its power to change Florida's boundary.6

In the last analysis I think that Florida's claim here could only be sustained on the view that Congress was under a duty to speak with reference to the State's boundary provision, failing which Congress' silence should as a matter of law be deemed the equivalent of acceptance of the provision. In light of factors already adverted to I cannot perceive how such a duty could be found to exist. To uphold Florida's claim on any such theory would be novel doctrine indeed, particularly where property rights of the United States are involved. Cf. United States v. State of California, supra, 67 U.S. at pages 39—40, 67 S.Ct. at pages 1668 1669. Moreover, to say that such a duty existed seems to me to misconceive the nature of the 'approval' of the constitutions of the seceded States contemplated by the reconstruction statutes. Such approval was not of the sort involved in the case of a constitution submitted to a constitutional convention for adoption or ratification, where the failure to reject a particular provision would be equivalent to its acceptance. Instead, the whole tenor of the reconstruction debates clearly shows that all that was meant by 'approval' was that before any seceded State was restored to representation, Congress must be satisfied that its constitution had been properly adopted and was republican in its general structure. That kind of a requirement of 'approval' does not lend itself to the conclusion that this Court would be attributing to the 1868 Congress a 'deceptive subtlety' unless it regards silence upon Florida's boundary provision as tantamount to its acceptance. Especially so, when that provision was quite outside the realm of matters upon which Congress had been called upon to act. 'Great acts of State' these events of the reconstruction period were indeed, but I do not think they can now be taken as having encompassed acceptance of the territorial pretensions of any particular State.

In sum, I believe the conclusion inescapable that all that Congress can properly be taken to have done in readmitting Florida was to declare that nothing in the State's new constitution disqualified its Senators and Representatives from taking their seats in Congress. While such action may in some abstract sense have constituted 'approval' of Florida's boundary provision, since it was included in its constitution, in my opinion it did not represent the sort of advertent, affirmative Congressional action which legally would have been necessary to effectuate an actual change in Florida's original admission boundary. It therefore did not 'approve' Florida's three-league boundary within the only sense contemplated by the Submerged Lands Act.

It is clear that the State fares no better on its alternative claim, based upon its original admission boundary. Since the Court does not reach this claim, it will be enough to state briefly the reasons which require its rejection.

The territory which now comprises the State of Florida was originally acquired by England from France and Spain by the Treaty of Paris of February 10, 1763.7 By the proclamation of October 7, 1763,8 King George III divided the acquired territory into East and West Florida. East Florida was declared to be 'bounded to the westward by the Gulf of Mexico and the Apalachicola river * * * and to the east and south by the Atlantic ocean and the gulf of Florida, including all islands within six leagues of the sea coast.' West Florida was declared to be 'bounded to the southward by the gulf of Mexico, including all islands within six leagues of the coast, from the river Apalachicola to Lake Pontchartrain. * * *'

By the Treaty of Versailles of September 3, 1783, England ceded to Spain the territory described merely as 'East Florida, as also West Florida.'9 By the Treaty of Amity, Settlement, and Limits of February 22, 1819, Spain ceded to the United States 'all the territories which belong to (Spain), situated to the eastward of the Mississippi, known by the name of East and West Florida.'10 Both the Act establishing Florida as a Territory,11 and the Act admitting it to the Union,12 describe it in terms of the territories of East and West Florida ceded by the Treaty of 1819.

Florida contends that the provision in King George's proclamation relating to all islands within six leagues of the coast was an assertion of a territorial boundary at that distance along the entire coast, and that subsequent conveyances necessarily incorporated that description. The opinion of the Court relating to Louisiana, Mississippi, and Alabama disposes of that contention (363 U.S. at pages 66—82, 80 S.Ct. at pages 997 1006), and what has been said there need not be repeated here.

Florida also relies on many of the same treaties as does Louisiana to show that this country's predecessors in title claimed large amounts of territorial sea. Without elaborating on what has already been said (363 U.S. at pages 73—74, 80 S.Ct. at pages 1001, 1002), it is sufficient to point out here that these treaties did not constitute territorial assertions, but merely established obligations between the parties of a special and limited nature, and varied so widely in the disstances specified as not to be of any value whatever in showing a uniform practice.

I would grant the Government's motion for judgment as to Florida.
